PURPOSE:To perform sterilization within an extremely short time and to generate no danger in handling, by injecting a gaseous mixture of gas or steam and air in a pressure resistant container receiving an article to be sterilized and igniting said mixture to explode the same. CONSTITUTION:The lid 4 of a pressure resistant container 2 is opened and an article to be sterilized is inserted in the container 2 to close the lid 4. The valve of a pipe 6 is opened to exclude the air in the pressure resistant container 2 by a vacuum pump and combustible gas is introduced into the container from a pipe 7 while the partial pressure preset corresponding to the pressure within an explosion limit is confirmed by a pressure gauge 13. Subsequently, air is introduced into the container 2 from a pipe 8 to be mixed with the combustible gas while stirred by a fan 5. When a high voltage current is allowed to flow to an ignition plug 12 in this state to generate a spark, the mixed gas explodes. The surface of the article 1 to be sterilized in the pressure resistant container 2 is brought into contact with the flame of about 2,000 deg.C generated by explosion for a short time of several hundred musec unit and all of bacterial thereon are killed.
