摘要： An electrode is used to perform discharge surface treatment of a work piece. The electrode is made of a green compact obtained by compression-molding an electrode material including powder of any of a metal, a metallic compound, and ceramics. The discharge surface treatment includes generating an electric discharge between the electrode and the work piece in an atmosphere of a machining medium and forming a film consisting of a machining material on a surface of a work piece using energy produced by the electric discharge. The powder has an average particle diameter of 5 micrometer to 10 micrometers, and contains 40 volume percent or more of a component not forming or less easily forming carbide as a component for forming the film on the work piece. The electrode has a hardness in a range of B to 8B tested with a pencil scratch test for a coating film.
