PROBLEM TO BE SOLVED: To provide a battery pack stacking a plurality of flat batteries, whose latitude for battery arrangement condition and wiring condition is improved. SOLUTION: A bus bar 222 for external connection is welded to the fifth negative terminal 1055. A fourth positive terminal 1044 is lead out in right-angle direction in relation to a fifth positive terminal 1045 and is connected with a right-angle bus bar 212. A fourth flat cell 10d is stacked on a fifth flat cell 10e. A third negative terminal 1053 is lead out in right-angle direction in relation to a fourth positive terminal 1054 and is connected with the right-angle bus bar 212. A third flat battery 10c is stacked on the fourth flat battery 10d. A second negative terminal 1052 is lead out in the same direction in relation to a third positive terminal 1043, and is connected directly with the third positive terminal 1043. A second flat battery 10b is stacked on the third flat battery 10c. A first negative terminal 1051 is lead out in the same direction in relation to a second positive terminal 1042, and is connected directly with the second positive terminal 1042. The first flat battery 10a is stacked on the second flat battery 10b. A bus bar 221 for external connection is welded to a first positive terminal 1041. Through these assembly processes, the battery pack 20 is constituted. COPYRIGHT: (C)2004,JPO |
