摘要： An electric discharge machining electrode adapted to improve the quality of a finished surface of a work by heightening a processing speed by improving an electric discharge generation rate η even in a fine machining process; and by rendering it possible to maintain the electric discharge generation rate η even when a time width and a voltage of the electric discharge pulses are reduced. In an electrode 1 for an electric discharge machining process carried out by generating electric discharge pulses between the electrode and a work 3, a radioactive metal is contained in the portion of the electrode in which the electric discharge pulses occur, or the portion thereof which is in the vicinity of the mentioned portion. The radiant rays emitted by the radioactive metal exerts influence upon materials existing between the work 3 and electrode 1, a so-called a processing liquid, usually pure water and oil, and works so as to promote the electrolytic dissociation of the mentioned materials therefrom. Therefore, the electric discharge generation rate η is improved.

摘要： A layered anisotropically conductive element (11), a resistant element (12), and a feed element (13) constitute an electrode (14) for discharge machining. The layered anisotropically conductive element (11) includes conductive layers and low-conductive layers alternately laminated on each other, the conductive layers and the low-conductive layers being made of thin metallic plates coated with an insulative film. The layered anisotropically conductive element (11) has an anisotropic conductivity, in which the conductivity in a direction parallel to the low-conductive layers is much higher than that in a direction perpendicular to the low-conductive layers. The resistant element (12) is connected to one of layer-perpendicular end surfaces (11c) of the layered anisotropically conductive element (11). The feed element (13) is connected to the resistant element (12).
