    摘要: An electric discharge machining apparatus in which at least either of a tool electrode or a workpiece is made of an anisotropic conductive material, includes, on a good conductive surface 20b of the anisotropic conductive material 2, a portion for connecting an isotropic conductive member 22. Electric discharge is generated on the good conductive surface 20b of the anisotropic conductive material 2. A conductive adhesive agent 23 is employed to bond the anisotropic conductive material 2 and the isotropic conductive member 22 to each other. The anisotropic conductive material is a pyrocarbon material. The pyrocarbon heat resolved carbon material is employed as a tool electrode material. Incombustible dielectric fluid, such as pure water, is employed as dielectric fluid. Moreover, there are provided apparatus for measuring voltage during electric discharge, apparatus for setting a threshold value for use to determine whether the electric discharge is normal electric discharge or abnormal electric discharge and apparatus for interrupting supply of a discharge current in a case where the measured discharge voltage is higher than the threshold value.
