<P>PROBLEM TO BE SOLVED: To provide a method for sterilization by which a sterilization effect can inexpensively and safely be improved without damaging a matter to be treated. <P>SOLUTION: Atmospheric pressure plasma is generated between a high pressure electrode 1 and a low pressure electrode 2 in an atmospheric pressure plasma generating apparatus to sterilize the surface of the matter G to be treated with the atmospheric pressure plasma. Gas to be used for the atmospheric pressure is gaseous mixture which contains as principal component at least one selected from a group of inert gas consisting of helium, neon, argon, krypton, xenon, radon, and nitrogen, and contains ethylene and oxygen. <P>COPYRIGHT: (C)2004,JPO |
