Abstract

PURPOSE: To improve efficiency of making a metallic thin wire by using as a pair of electrodes two points spaced apart from each other on a bundle of conductive wires and leaving one required conducive wire uncut to form a metallic thin wire by cutting-and-removing, between the electrodes, covering matter around the bundle of the conductive wires. CONSTITUTION: Cuts 20a are made in covering matter 20 between two points spaced apart from each other on a bundle 11A of conductive wires to remove the covering matter, and the two points are used as a pair of electrodes 8, 8, and then unnecessary wires 11a of the conductive wires 11a constituting the bundle 11A are cut-and-removed and one conductive wire 11a is left uncut to form a metallic thin wire 3. The metallic thin wire 3 thus made is installed within a demolishing container, and the demolition container is filled with water, and an energy supply circuit is connects to the electrodes 8, 8. When electric energy stored in a capacitor is applied to the metallic thin wire 3 in a short period of time through the electrode 8, 8, the metallic thin wire 3 is rapidly fused and vaporized to vaporize water and impact occurring at this moment destroys a matter to be demolished. A particular metallic thin wire need not be installed separately so that efficiency of operation is enhanced.
