Abstract
An electroplating method calls for immersing a body to be plated in a plating solution containing tin and bismuth to form a tin-bismuth alloy skin layer on surfaces of the body. The plating is carried out such that a solid tin metal and a solid bismuth metal placed in the plating solution are connected to an anode and the body to be plated is connected to a cathode of a power supply.
