    摘要: An object is to provide an electroless plating process which can thin a film thickness of a nickel film and can obtain a film having excellent mounting characteristics, when the nickel film and a gold film are sequentially formed on a surface of a copper material. In order to solve the above-mentioned problems, provided is an electroless plating process which sequentially forms a nickel film and a gold film on a surface of a copper material by an electroless plating method and includes: a step of forming the nickel film on the surface of the copper material by an electroless strike plating method; and a step of forming the gold film by a reduction-type electroless plating method.
