Abstract
A rechargeable battery is integrated with a battery protection circuit that protects the rechargeable battery from overcharging, over discharging, and so forth. A circuit board (9) on which are formed a battery protection circuit, a positive input and output terminal (4), and a temperature detection terminal (6) is disposed on a rechargeable battery (10) via a spacer (13), and the positive and negative electrodes of the rechargeable battery (10) are connected to the circuit board (9). This assembly is enveloped by a cover cap (15) and a cover plate (14), such that the positive input and output terminal (4) and the temperature detection terminal (6) are exposed to the outside through openings provided in the cover plate (14), and one end of the cover cap (15) in the same plane as these is used for connection as a negative input and output terminal (5).
