Abstract

A battery pack includes a stack of a plurality of battery cells each including positive and negative electrode lead tabs led out of a laminate film casing, and a coupling assisting member. The coupling assisting member includes a conductive plate member fixing portion that fixes a conductive plate member having first and second main surfaces in a front-to-back relationship. Either one of the positive and negative lead tabs of one battery cell is conductively connected to the first main surface of the conductive plate member. A lead tab of a battery cell adjoining the one battery cell, having a polarity different from that of the lead tab of the one battery cell, is inserted through the second slit portion and conductively connected to the second main surface of the conductive plate member. Vibration transmission ratio changing bends are provided on the lead tabs.
