PROBLEM TO BE SOLVED: To secure excellent vibration-resistant performance to properly use a battery pack even in an environment easy to receive vibration from the outside like a vehicle or the like, in a battery pack having a structure wherein a laminate battery is used as a unit battery, and a positive electrode tab and a negative electrode tab of the laminate batteries adjacent to each other are connected to each other by a bus bar. SOLUTION: The bus bars 20 for serially connecting a plurality of the laminate batteries 10 each being the unit battery, a positive electrode tabs 13 and a negative electrode tabs 14 of the laminate batteries 10 connected by the bus bars 20, and flanges of a battery armor 11 in the vicinity of the positive electrode tabs 13 and the negative electrode tabs 14 are integrally supported by support members 30. Thereby, when vibration is transmitted from the outside, the bus bars 20 and the laminate batteries 10 are integrally vibrated, so that inconvenience that a crack is generated in the positive electrode 13 or the negative electrode 14 by stress in vibration can effectively be avoided.
