摘要： PROBLEM TO BE SOLVED: To manufacture a welded structural member by stably forming a large nugget in the interface of members to be welded by using one-side resistance spot welding by which the members to be welded are pressurized from one side without using a back bar and a back bar electrode even when the members to be welded are metal sheets having low rigidity. SOLUTION: When performing the one-side resistance spot welding in which a second member 2 to be welded is energized through an electrode tip 3 for spot welding which abuts on the surface of the second member 2 to be welded which is arranged by being superposed on a first member 1 to be welded, a projecting part 4 which is convex toward the side of the second member 2 to be welded is formed in a position of the first member 1 to be welded, the position being opposite to a position where the electrode tip 3 for spot welding abuts on the second member 2 to be welded.
