ABSTRACT:
An electrode for electric discharge surface treatment, in which a pulse-like electric discharge is caused between the electrode and a work in a dielectric fluid or an atmosphere, and in which a coat of an electrode material or a substance that is generated by a reaction of the electrode material due to an electric discharge energy is formed on a surface of the work, is a molded powder that is formed by molding a material powder including a metallic powder, a metallic compound powder, and a conductive ceramic powder. A powder solid that is formed as a result of coagulation of the material powder, and that is included in the molded powder has a diameter shorter than a distance between the electrode and the work.
