PROBLEM TO BE SOLVED: To efficiently utilize a space on the inside of a battery pack and reduce the number of components. SOLUTION: Each of electrode terminal leads 3, 4 interposed between outer jacket materials 2 is taken out to the outside and then a unit cell is sealed, side walls 14a, 14b interposing a thermal bonding part 12c from which the electrode terminal leads 3, 4 are taken out are formed by bending the outer jacket material 12, and parts positioning on both sides of the thermal bonding part 12c of the side walls 14a, 14b are turned inward. Thus, one circuit board can be installed so as to extend over a plurality of thermal bonding parts 12c. COPYRIGHT: (C)2005,JPO&NCIPI
