摘要:
There are provided a tin-plated product which has a zinc plating layer on the surface thereof and which has good corrosion resistance and good adhesion of the zinc plating even if the connecting portion of a terminal of the tin-plated product to an electric wire of aluminum or an aluminum alloy is not processed during press fitting such as swaging (or caulking) when the tin-plated product is used as the material of the terminal which is to be connected to the electric wire by press fitting, and a method for producing the same. The tin-plated product has: a base material 10 of copper or a copper alloy; a tin containing layer 12 formed on the surface of the base material 10, the tin containing layer 12 having a copper-tin alloy layer 121 and a tin layer 122 of tin which is formed on the surface of the copper-tin alloy layer 121 and which has a thickness of not larger than 5 μm; a nickel plating layer 14 formed on the surface of the tin containing layer 12; and a zinc plating layer 16 serving as the outermost layer formed on the surface of the nickel plating layer 14.
