PROBLEM TO BE SOLVED: To provide a radiator having a plated layer thereon which is formed by coating a surface of an aluminum member with Zn, Ni and Sn and has further improved wettability of solder. SOLUTION: The radiator 11 has the improved wettability of solder due to the plated layer formed thereon by coating the surface of the aluminum member with Zn, Ni and Sn, wherein the plated layer is formed so that a Zn weight ratio occupying in the whole weight is controlled to 0.16-0.24%, an Ni weight ratio occupying in the whole weight is controlled to 2.72-2.94%, and an Sn weight ratio occupying in the whole weight is controlled to 0.43-0.50%, and the plated layer is further coated with a urethane resin so that the weight ratio of the urethane resin occupying in the whole weight is controlled to 0.02-0.08%.
