PROBLEM TO BE SOLVED: To provide a solder alloy capable of preventing deterioration in the tip of a soldering iron. SOLUTION: This solder alloy has a composition containing, by weight, 0.3 to 3% Cu, 0.01 to 0.1% Fe and 0.001 to 0.004% Ga, and the balance Sn with inevitable impurities. Further, at least one or more kinds selected from 0.1 to 4.5% Ag, 0.05 to 0.5% Ni, 0.1 to 3.0% Bi and 0.001 to 0.01% Mn are added to the solder alloy, thus its mechanical properties are improved.
