Abstract
There is provided an inexpensive plated product, which can prevent the increase of the contact resistance of a silver-plating film and the change of the color of the surface thereof after reflow-treating a plated product wherein the silver-plating film is formed on a portion of the surface thereof and wherein a tin-plating film is formed on a portion of the other portion of the surface thereof, and a method for producing the same. The plated product is produced by a method including the steps of: forming a nickel-plating film 12 on a surface of a base material 10 of copper or a copper alloy; forming a silver-plating film 16 on a portion of a surface of the nickel-plating film 12, and forming a tin-plating film 20 on a portion of the other portion of the surface of the nickel-plating film 12, to prepare a plated product which has the silver-plating film 16 and the tin-plating film 20 on the surface of the nickel-plating film 12 formed on the base material 10; and irradiating the surface of the plated product with infrared rays to heat the surface thereof to reflow-treat the tin-plating film 20 to cause the tin-plating film 20 to be a reflowed tin-plating layer 22.
