Claim:
1. A method of forming a welded structure in a battery, comprising: arranging a second conductive member, made of a second material different from that of a first material of a first conductive metal member, on a surface of a metal plating layer which is formed on a surface of the first conductive metal member, the second conductive metal member extending a first length along the surface of a metal plating layer from an outer periphery of the first conductive metal member to a tip portion of the second conductive metal member having a shape defined by (i) a top surface extending a portion of the first length and (ii) an edge extending a tip height from the metal plating layer to the top surface; controlling an output of laser light irradiated to the second conductive metal member to:
