Abstract

In order to provide a battery in which a molded section can be fixed to a battery cell, a battery comprises a battery cell, a circuit board which is attached to the battery cell, an electrode terminal which connects the battery cell and the circuit board electrically, a molded section which adheres the circuit board and the electrode terminal to the battery cell as an entire unit, adhesion strengthened areas which are formed between the electrode terminal and the battery, and electrode terminal inner surface resin sections which are formed in a part of the molded section of the adhesion strengthened area.

Claims

1. A battery comprising

a battery cell;

a circuit board which is attached to the battery cell;

an electrode terminal which connects the battery cell and the circuit board electrically;

a molded section which adheres the circuit board and the electrode terminal to the battery cell as an entire unit;

an adhesion strengthened area which is formed between the electrode terminal and the battery;

an electrode terminal inner surface resin section which is formed in a part of the molded section of the adhesion strengthened area.

2. A battery according to claim 1, wherein

a through-hole is formed on the electrode terminal in a direction toward the battery cell;

a connecting resin section is filled and formed in the through-hole so as to connect a resin section on an outside of the electrode terminal and the electrode terminal inner surface resin section.

3. A battery according to claim 1 wherein the electrode terminal comprises:

a first adhesion section which is adhered to the battery cell;

a standing edge section which extends in a direction from the surface of the battery cell towards a far side;

an extracted section which is attached to the standing edge section and extends along the surface of the battery cell; and

a second adhesion section which is disposed to be connected with the extracted section and fixed on the circuit board.
