A film formation method includes preparing a substrate formed a Co film as a seed layer on a surface of the substrate, applying a negative voltage to the substrate such that a surface potential of Co is lower than an oxidation potential of the Co, and in a state when the negative voltage is applied to the substrate, dipping the Co film in a plating solution mainly containing copper sulfate solution, thereby a Cu film is formed on the Co film of the substrate by electroplating.
