Abstract

An apparatus which is constituted to supply electrical energy to a melting and vaporizing material (for example metal wire 6) so as to cause the melting and vaporizing material to melt and vaporize, thereby demolishing an object to be demolished (such as concrete 2) using the vaporization and expansion force generated at the time of melting and vaporization of the material; wherein either by providing a granular material 8 which ejects from a container following the generation of the vaporization and expansion force, or by using an inflammable material as demolishing material 46 in which the melting and vaporizing material is immersed, a to-be-demolished object is demolished with a strong demolishing force.
