Claim 0:
1. A terminal component that is to be attached to a battery case so that a part of the terminal component is connected to an internal terminal inside the battery case, and a part is exposed to an outside of the battery case, the terminal component comprising:
a first metal and
a second metal overlapped on and in direct contact with the first metal, wherein
the first metal has a part to be connected to the internal terminal, and the second metal has a part to be exposed to the outside of the battery case,
at a planar interface where the first metal and the second metal are overlapped and in direct contact with each other,
one of the first metal and the second metal has a protrusion having a flat top portion at a distal end of the protrusion, and the other of the first metal and the second metal is joined directly to the flat top portion along the planar interface,
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,
the first metal and the second metal are configured of different metals, and
the first metal and the second metal are metal-joined at the distal end of the protrusion.
