PROBLEM TO BE SOLVED: To provide an electrode for a device for discharge crushing to easily generating discharge. SOLUTION: In the electrode 1 of the device for discharge crushing, a pressure wave is generated by making an electrolyte to plasma by imparting a discharge energy to the electrolyte 63 provided on an inner side of an object 60 to be crushed through the electrode 1 and the object to be crushed is crushed by the pressure wave. The electrode 1 comprises: an internal conductor shaft 2; a cylindrical insulation body 3 for covering an outer periphery of the internal conductor shaft; and an outer conductor 4 provided on an outer periphery of the cylindrical insulation body. A tip end side discharge gap 8 for generating discharge by a distal end part (distal end part 5t) of the outer conductor 4 (outer conductor constitution body 5) and a distal end part 2t of the internal conductor shaft 2 exposed from the cylindrical insulation body 3 is formed. The distal end part of the outer conductor is divided to a plurality of parts in a circumferential direction of the outer conductor. COPYRIGHT: (C)2006,JPO&NCIPI |
