PROBLEM TO BE SOLVED: To provide a method for discharge crushing capable of efficiently crushing a plurality of object positions to be crushed without requiring a labor and a time. SOLUTION: A device is used as a connection device 2, which has an electric connection part of connection elements 3;4 connected to an electrode 1 by electric wires 5;6 and in which an electric wire (power source cable 20) from a discharge control device (pulse power source 80) is connected to the electric connection part. A plurality of electrodes are arranged at a plurality of different discharge object positions to be discharge-crushed (electrolyte filling hole 61) of the object 60 to be crushed and connection elements of the plurality of electrodes 1 are successively connected to the electric connection part of the connection device 2. The object 60 to be crushed is crushed by successively crushing the object positions to be discharge-crushed by discharge. COPYRIGHT: (C)2006,JPO&NCIPI
