PROBLEM TO BE SOLVED: To provide a metal member welding structure capable of increasing welding strength by suppressing growth of an intermetallic compound between a steel material and a plated layer. SOLUTION: In the metal member welding structure for joining a first metal member to a second metal member with solder, at least one of the first and second metal members is an Sn-based plated steel sheet, the solder contains no Pb, but composed mainly of Sn, and contains one, or two or more of, by mass,≥0.3% to≤1.0% Ni,≥0.1% to≤1.5% Co, and≥0.5% to≤1.0% Fe.
