PROBLEM TO BE SOLVED: To assemble so that an excessive force is not applied to a lead plate and its connecting part while accurately arranging at a fixed position of a sheath case both a polymer battery and a terminal board low in dimension precision. SOLUTION: A battery pack is equipped with the sheath case 6, the polymer battery 1 housed in this sheath case 6, and the terminal board 2 which is connected to this polymer battery 1 via a lead plate 3, and in which an output terminal 7 arranged and installed at the fixed position of the sheath case 6 and fixed to a surface is exposed at the exterior of the sheath case 6. The lead plate 3 has a bellows-shaped connection piece 16 connected to the terminal board 2, and the end part of the bellows-shaped contact piece 16 is fixed to the terminal board 2. In the battery pack, the terminal board 2 is electrically connected to the polymer battery 1 via the lead plate 3 having the bellows-shaped contact piece 16. COPYRIGHT: (C)2009,JPO&INPIT
