Abstract: A terminal component includes a first metal and a second metal overlapped on the first metal, the first metal having a part to be connected to an internal terminal, and the second metal having a part to be exposed to the outside of a battery case. At an interface where the first metal and the second metal are overlapped, one of the first metal and the second metal has a protrusion having a flat top portion. The other metal is joined to the top portion. A cross section of the protrusion orthogonal to a projection direction of the protrusion is set such that fusing occurs when a current equal to or higher than a predetermined current value flows between the first metal and the second metal.
