A thick film of metal, a metal compound, or ceramics is formed. SOLUTION: A pulsed discharge is generated between a workpiece and a green compact electrode obtained by compression molding a metal powder, a metal compound powder, or a ceramic powder, and an electrode material or In the discharge surface treatment in which the electrode material forms a film made of a substance reacted by discharge energy, a metal or a metal compound having a thermal conductivity of 10 W / mK or more, or a ceramic powder is used as the material for the green compact electrode. The electrode is manufactured. [Selection] Figure 3 |
