A lead material for an electronic part having no adverse effect on the environment, having excellent solderability, desirable welding strength during welding and a low degree of nonuniform thickness of the plated layer during reflow processing. The lead material has a first plated layer and a second plated layer, both of which do not contain Pb, laminated on the surface of a conductive substrate in such order. The melting point of the second plated layer is lower than that of the first plated layer. The first and second plated layers are made of a Sn substance and a Sn alloy, respectively or vice versa.
