PROBLEM TO BE SOLVED: To provide a photocatalytic-function building material and a manufacturing method therefor, which prevent a photocatalytic-function material from being buried in or covered with a coated film in a method for applying a coating containing the photocatalyst-function material, and which enhance antibacterial characteristics, antifouling characteristics, organic-matter decomposing characteristics and the like, brought about by a photocatalytic function. SOLUTION: The coating including the photocatalytic-function material (2), a material which can be foamed by heating, and a binder component (3) which is composed of an inorganic-organic composite binder, is applied onto a surface layer of the building material, heated and dried; and the material for being foamed by heating is foamed so that the coated film (1) can be set to have a porous structure. Thus, the material (2) is exposed on a surface so that the photocatalytic-function building material can be manufactured. COPYRIGHT: (C)2004,JPO
