The adhesive tape 24 fastens the plural single-batteries 100. The plural single-batteries 100 may be fixed using a heat-shrinkable tape in place of the adhesive tape 24. In this case, the protective sheets 33 are arranged on both side surfaces of the battery module 200, and the heat-shrinkable tape is wound around the battery module 200 and protective sheets 33. After that, the heat-shrinkable tape is shrunk by heating to bundle the plural single-batteries 100.
One end of the positive electrode-side lead 22 is connected to the positive electrode terminal 7 of the single-battery 100 located lowermost in the stack of the single-batteries 100. One end of the negative electrode-side lead 23 is connected to the negative electrode terminal 6 of the single-battery 100 located uppermost in the stack of the single-batteries 100.
A printed wiring board 34 is disposed on the one inner surface along the short-side direction of inner surfaces of the housing container 31. The printed wiring board 34 includes a positive electrode-side connector 341, a negative electrode-side connector 342, a thermistor 343, a protective circuit 344, wirings 345 and 346, an external power distribution terminal 347, a plus-side (positive-side) wire 348a, and a minus-side (negative-side) wire 348b. One main surface of the printed wiring board 34 faces the surface of the battery module 200 from which the negative electrode terminals 6 and the positive electrode terminals 7 extend out. An insulating plate (not shown) is disposed in between the printed wiring board 34 and the battery module 200.
