Abstract:
A method of forming an oxide film on a surface of a copper alloy, including the steps of providing a copper alloy including copper and an element selected from the group consisting of Mn, Zn, Ga, Li, Ge, Sr, Ag, Ba, Pr and Nd, and diffusing atoms of the element to a surface of the copper alloy so as to form an oxide film on the surface of the copper alloy,wherein a concentration of the element in the copper alloy is more than 0.1 and not more than 20 atomic percentage and within a solubility limit of the element in the copper.
