Abstract

The invention relates to a plate-like electronic member, e.g., an electro luminescence element or the like, and an electronic device. In the electronic member (1) of the invention, first and second electrodes are formed on respective surface of a plate-like electronic member body a first electrode connecting portion is formed on the first electrode, and, a second electrode connecting portion which is electrically connected with the second electrode is formed on a same side of the first electrode as the first electrode connecting portion with an insulating layer disposed between the second electrode connecting portion and the first electrode. The electronic device according to the invention comprises the electronic member (1) and an apparatus case (15) having the electronic member built-in.

Claims

1. An electronic device comprising:

a circuit board having an electrically connecting portion;

an electronic member which is arranged to face the circuit board and which has an electrode formed at a position corresponding to the connecting portion; and

a conductive projecting portion which is formed on the connecting portion so as to electrically connect the electrode of the electronic member with the connecting portion of the circuit board.

2. An electronic device comprising:

an electronic member comprising a plate-like electronic member body, a pair of first and second electrodes which are formed on both surfaces of the electronic member body, and a pair of first and second electrode connecting portions which are disposed on a same side of the first electrode and which are electrically connected with the pair of first and second electrodes, respectively, wherein the second electrode connecting portion is formed on the first electrode with an insulating layer disposed therebetween;

a circuit board which is disposed to face the electronic member and which has a pair of terminal portions formed to face the pair of electrode connecting portions; and

conductive projecting portions which are formed on the terminal portions of the circuit board so as to electrically connect the electrode connecting portions with the terminal portions.

3. An electronic apparatus comprising an apparatus case having an electronic device built-in, the electronic device comprising:

a circuit board having an electrically connecting portion;

an electronic member which is arranged to face the circuit board and which has an electrode formed at a position corresponding to the connecting portion; and

a conductive protecting portion which is formed on the connecting portion so as to electrically connect the electrode of the electronic member with the connecting portion of the circuit board.
