Abstract

A method for welding copper-including members includes laser-welding a first member that includes copper, and a second member that includes copper and is located adjacent to the first member. A welding surface of the first member and a welding surface of the second member are melted by moving an irradiation position of a laser to turn in a spiral shape while approaching a center of the spiral when irradiating the laser on the welding surface of the first member and the welding surface of the second member.
