A metal plate and an electrode in a polymer lithium ion secondary battery or the like are welded certainly, and it is accomplished to further improve the reliability and the durability thereof. Each of an upper metal plate () and a lower metal plate () on the positive pole/terminal is welded to a pole/terminal of positive electrode () so that the pole/terminal of positive electrode () may be sandwiched from each of the upper and lower sides. Moreover, each of an upper metal plate () and a lower metal plate () on the negative pole/terminal is welded to a pole/terminal of negative electrode () so that the pole/terminal of negative electrode () may be sandwiched from each of the upper and lower sides. This eliminates occurrence of poor welding in the electric resistance welding.

There is disclosed a battery pack, which has a plate-shaped resin-formed body to divide an internal space of the battery pack into at least two spaces in a thickness direction thereof, so that a battery is received in a first internal space, while a wiring substrate having a control circuit packaged thereon is placed in a second internal space, thereby allowing the battery pack to hold an input/output circuit or the like of a memory card securely in a limited space in the battery pack, while ensuring that a sufficient insulation is provided to the battery, when the battery pack is used for PDA'S, for instance.
