<P>PROBLEM TO BE SOLVED: To provide an air cleaner, preventing increase in size, simple in constitution, and causing complete extinction of floating microbes, virus and mildew spores contained in the air. <P>SOLUTION: In this air cleaner 11, as a filter for passing the air, a porous glass film (SPG film) controlled to be substantially uniform in pore size in the range of 100 nm to 20 μm is used, the porous glass film is formed like a pipe to obtain the SPG pipe 1, one end part of the pipe is sealed, and the air is let flow in from the other end part, whereby the air can be easily passed through the porous glass film (the pipe wall) 2 to catch microbes, virus and spores in the air in the penetrating pores. The film 3 of a metal heating unit is formed on the surface of the SPG pipe 1 by plating, and an electric current is applied to the metal heating unit 3 to heat the whole porous glass film, whereby the microbes, virus and spores caught in the penetrating pores of the porous glass film 2 are heated to cause extinction. <P>COPYRIGHT: (C)2005,JPO&NCIPI
