Zusammenfassung:	PROBLEM TO BE SOLVED: To mutually join coated metal plates without necessitating any masking in the case of peeling of a coat and coating and moreover without using another piece of metal plate. SOLUTION: In the electric welding method for mutually joining coated metal plates 25, 26 whose surfaces are non-conductive surfaces on which insulating coats 21, 22 are formed and whose back surfaces are conductive surfaces by electric welding, such a folded part 29 that the conductive surface exposes in the surface side is formed in one side of coated metal plate 26, the conductive surface of the folded part 29 formed in the end part of one side of coated metal plate 26 is electrically brought into contact with the back surface side conductive surface of the other side of coated metal plate 25, and electric welding is executed by applying voltage between the conductive surface of one side of coated metal plate 26 and the conductive surface of the other side of coated metal plate 25.
