PCT No. PCT/JP96/02060 Sec. 371 Date Jan. 23, 1998 Sec. 102(e) Date Jan. 23, 1998 PCT Filed Jul. 22, 1996 PCT Pub. No. WO97/03796 PCT Pub. Date Feb. 6, 1997A method comprising a step to form a hole (2) for charging a breaking substance (4) into an object to be fractured (1), a step to insert a pair of electrodes (6) having a thin metal wire (5) connected between ends thereof into the hole (2), a step to dispose the breaking substance (4) and the thin metal wire (5) into a bag-like container (22) made of rubber at a stage to supply electric energy accumulated in a capacitor to the electrodes (6) for fusing and vaporizing the thin metal wire (5), thereby swelling a volume of the breaking substance (4) and breaking the object to be fractured (1), and a step to fit the bag-like container (22) into the hole (2). This method assures secure transmission of an expansion force to the object to be fractured even when the hole formed in the object to be fractured is deformed.
