ABSTRACT:
A battery pack having a battery in which a battery case and a cap of a sealing plate sealing an open end of the battery case serve as connection electrodes of opposite polarities, a terminal unit including external connection terminals respectively connected to these connection electrodes and an insulating cover integrally formed therewith, the terminal unit covering at least one end of the battery case, and a resilient member interposed between one end of the battery case and the terminal unit in a compressed state. In the manufacturing method of this battery pack, the dimension between the terminal unit and the other end of the battery case is controlled when fixing the terminal unit with the battery case. The battery pack thus has a simple and low cost configuration and yet exhibits high reliability in terms of the connection state of the external connection terminals when set in a portable electronic device.
