PROBLEM TO BE SOLVED: To provide a coating for electric appliances which is improved in the arc resistance by forming a coating layer on a member constituting an electric appliance, and a manufacturing method thereof. SOLUTION: The coating layer 2 of a metal having the melting point higher than that of a metal base material 1 is formed on the metal base material. A6061 or C1020 is used for the base material 1. For the coating layer 2, 13Cr stainless steel is used. The coating layer 2 is formed by using the thermal spraying method. The angle formed by a free edge and the base material 1 at an end of the coating layer 2, i.e., the groove angle 3 of the coating layer 2 is formed to be 30 deg., and the wall thickness of the coating layer 2 is formed to be 3 mm.
