Abstract

A thermoelectric generation module having: a base material; a plurality of electrodes disposed on the base material; and a thermoelectric conversion layer that coats each of the electrodes individually leaving a portion of the electrode to which a wiring is to be connected, wherein the thermoelectric conversion layer adheres to the base material around the electrode excluding the portion of the electrode to which the wiring is to be connected.

Claims

1. A thermoelectric generation module having:

resin film;

a plurality of electrodes disposed on the resin film; and

a thermoelectric conversion layer having a resin layer that coats each of the electrodes individually leaving a portion of the electrode to which a wiring is to be connected,

wherein the thermoelectric conversion layer having a resin layer adheres to the resin film around three sides of the electrode coated by the thermoelectric conversion layer having a resin layer excluding the portion of the electrode to which the wiring is to be connected, and

wherein the thermoelectric conversion layer having a resin layer protrudes around the electrode in three directions.

2. The thermoelectric generation module as claimed in claim 1, wherein the thermoelectric conversion layer having a resin layer adheres to the resin film around three sides of the electrode below the wiring that is connected to the thermoelectric conversion layer having a resin layer.

3. The thermoelectric generation module as claimed in claim 2, wherein a width of an adhered portion of the thermoelectric conversion layer having a resin layer and the resin film is wider than a thickness of the thermoelectric conversion layer.

4. The thermoelectric generation module as claimed in claim 1, wherein an easy adhesion layer lies between at least the resin film and the thermoelectric conversion layer having a resin layer, and wherein the thermoelectric conversion layer having a resin layer adheres, via the easy adhesion layer as an adhesion layer, to the resin film around three sides of the electrode excluding the portion of the electrode to which the wiring is to be connected.

5. The thermoelectric generation module as claimed in claim 1, wherein a conductive resin layer lies between at least the resin film and the electrode and the thermoelectric conversion layer having a resin layer, and wherein the thermoelectric conversion layer having a resin layer adheres, via the conductive resin layer as an adhesion layer, to the resin film of the electrode and around three sides of the electrode excluding the portion of the electrode to which the wiring is to be connected.

6. The thermoelectric generation module as claimed in claim 5, wherein electric conductivity of the thermoelectric conversion layer having a resin layer is higher than the conductive resin layer.

7. The thermoelectric generation module as claimed in claim 1, wherein a background surface of the thermoelectric conversion layer having a resin layer, that is the side of at least the thermoelectric conversion layer having a resin layer to be adhered, has an energy ray-irradiated surface-modified face, and wherein with the use of the surface-modified face as an adhesion surface, the thermoelectric conversion layer having a resin layer adheres to the resin film around three sides of the electrode excluding the portion of the electrode to which the wiring is to be connected.

8. The thermoelectric generation module as claimed in claim 1, wherein the wiring electrically connects the thermoelectric conversion layer having a resin layer with a portion of an other electrode to which the wiring is to be connected, wherein the other electrode is adjacent to the electrode coated by the thermoelectric conversion layer having a resin layer.

9. The thermoelectric generation module as claimed in claim 1, mounting a secondary battery that is electrically connected to an output portion of the thermoelectric conversion layer having a resin layer.
