PROBLEM TO BE SOLVED: To provide a battery pack which improves volumetric efficiency to reduce manufacturing costs. SOLUTION: The battery pack includes leads on which positive terminals and negative terminals disposed on the same side of batteries are led out, and walls made by erecting the edges of leads opposite to each other against the leads. The battery pack also includes a plurality of batteries lined up in a single direction, and cutouts formed in locations that avoid the walls. When a connection board is connected to the batteries, part of the board is so located on the leads that the cutouts avoid the walls of the batteries. The connection board and a circuit board can be connected and disconnected via a connection. COPYRIGHT: (C)2008,JPO&INPIT |
