PROBLEM TO BE SOLVED: To provide a production method capable of producing a copper oxide-containing member with a cuprous oxide film having a film thickness of about several μm at a low cost and a copper oxide film-containing member.SOLUTION: A method for producing a copper oxide film-containing member includes: a step of preparing a base body 1 in which at least a surface layer 2 contains Cu; a step of sticking a solution containing lithium ions (Li) and halogen element ions to the surface layer 2 of the base body 1; and a step of forming a film 3 comprising CuO by heat-treating the base body 1 at a heating temperature of 50-200°C in an atmosphere having a relative humidity of ≥60%. |
