Abstract
A thin metal wire 8 is fused and vaporized by a predetermined amount of electrical energy supplied to the thin metal wire 8 for a short period of time, whereby a blasting substance 3 is expanded in volume. Therefore, a vaporization expansion force caused by the fusion and vaporization of the thin metal wire 8 moves a shock delivering member 22, so that the shock delivering member 22, colliding with a to-be-blasted object H1, delivers a shock to the to-be-blasted object H1, thereby blasting the to-be-blasted object H1.
