PROBLEM TO BE SOLVED: To provide a new high-melting point leadless solder alloy the melting starting point (liquidus temperature) of which is≥280°C and the melting starting temperature (solidus temperature) of which is≤350°C. SOLUTION: The Mg-based solder alloy contains, by mass, 0 to 8% Al, 37 to 45% Zn and 0.5 to 3% Ga, and the balance Mg with inevitable impurities. Since the Mg-based solder alloy has a melting point (liquidus temperature) of≥280°C and a melting starting temperature (solidus temperature) of≤350°C, it can be preferably used as leadless solder having a high melting point instead of Sn-95Pb.
