    Abstract: PROBLEM TO BE SOLVED: To provide a photocatalyst film which has high cohesiveness with a photocatalyst action layer and supporter and has excellent durability against deterioration due to the photocatalyst action and which is excellent in its sustenability, and to provide a manufacturing process of the phtocatalyst film. SOLUTION: The photocatalyst film is characterized by being provided with a supporter, an organic-inorganic composite layer comprising a cross-linking structure formed by hydrolysis and condensation polymerization of an alkoxide of an element selected from Si, Ti, Zr and Al in a graft polymer layer comprising a graft polymer chain that is directly bonded to the surface of the supporter and the photocatalytic activity layer in this order. The manufacturing method of the same is also obtained. COPYRIGHT: (C)2008,JPO&INPIT
