    摘要: A layered anisotropically conductive element, a resistant element, and a feed element constitute an electrode for discharge machining. The layered anisotropically conductive element includes high conductivity layers and low conductivity layers alternately laminated on each other, the high conductivity layers and the low conductivity layers being made of thin metallic plates coated with an insulating film. The layered anisotropically conductive element has an anisotropic conductivity, in which the conductivity in a direction parallel to the low conductivity layers is much higher than that in a direction perpendicular to the low conductivity layers. The resistant element is connected to one of end surfaces of the layered anisotropically conductive element perpendicular to the layers. The feed element is connected to the resistant element.

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.
