Abstract
There is provided a tin-plated product having an excellent minute sliding abrasion resistance property when it is used as the material of insertable and extractable connecting terminals, and a method for producing the same. After a nickel layer 16 is formed on a substrate 10 of copper or a copper alloy so as to have a thickness of 0.1 to 1.5 μm by electroplating, a tin-copper plating layer 12 containing tin 12b mixed with a copper-tin alloy 12a is formed thereon so as to have a thickness of 0.6 to 10 μm by electroplating using a tin-copper plating bath which contains 5 to 35% by weight of copper with respect to the total amount of tin and copper, and then, a tin layer 14 is formed thereon so as to have a thickness of 1 μm or less by electroplating if necessary.
