<P>PROBLEM TO BE SOLVED: To provide a method for producing a photocatalytic body in which photocatalytic particles are firmly bonded onto a resin substrate without damaging the photocatalytic function of the particles and the particles are hardly separated from the substrate and the resin substrate is hardly deteriorated even when used for a long term. <P>SOLUTION: This method is provided for producing a fine particle-fixed body by bonding the photocatalytic fine particles onto the substrate according to chemical bonding of a silane coupling agent to the surface of the substrate, wherein a thin film of the silane coupling agent having unsaturated bonds is formed on the surface of the photocatalytic fine particle, the thin film formed on the surface of the photocatalytic fine particle is brought into contact with a resin surface of the resin substrate and the resin surface is chemically bonded to unsaturated bonds existing in the thin film. Here, it is preferable that graft polymerization is used for the chemical bonding and that radiation graft polymerization is used for the graft polymerization. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
