Abstract
A fusible and vaporizable substance (for example, a thin metal wire is used) 2 is fused and vaporized by supplying thereto a predetermined amount of electrical energy from a capacitor 14 of an electrical energy supply circuit 10 for a short period of time, and nitromethane 3 is detonated by a phenomenon in the process in which the fusible and vaporizable substance 2 fuses and vaporizes, so that an object to be blasted 4 is reliably blasted by this detonation force.
