Abstract

A positive electrode collector has a part connected to a positive electrode terminal and a part connected to a positive electrode tab. In the positive electrode collector, a fuse portion is provided between the part connected to the positive electrode terminal and the part connected to the positive electrode tab. In the positive electrode collector, a region closer to the part connected to the positive electrode terminal than the fuse portion is referred to as a first region, and a region closer to the part connected to the positive electrode tab than the fuse portion is referred to as a second region. An insulating plate as an insulating member disposed between the positive electrode collector and an electrode body is connected to the second region, and the second region is prevented from moving toward the first region after the fuse portion blows.
