Patent ID: 6929879

Claim:
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; space which serves for an adhesion strengthened area, the space formed between the electrode terminal and the battery cell by injecting a resin in a molding operation; an electrode terminal inner surface resin section which is formed by the resin which is injected into the space as a part of the molded section, wherein the circuit board is disposed on and attached on the battery cell, the electrode terminal has a first adhesion section attached to a terminal of the battery cell, a second adhesion section attached to a terminal of the circuit board, a standing edge section which stands on the first adhesion section so as to be in a direction in which the standing edge section should be away from the first adhesion section, and an extracted section connecting the standing edge section and the second adhesion section, the space is formed between the extracted section and the battery cell, and the circuit board and the electrode terminal are embedded in the resin by performing the molding operation.
