A photocatalytic functional material having an excellent photocatalytic activity even by a low temperature heat treatment and having a high mechanical strength of the surface. The functional material comprises a photocatalyst, an electron capturing metal and a surface layer (photocatalytic functional layer) containing a matrix having resistance to photodegradation. Though the major proportion of the photocatalyst (TiO2 particles, etc.) in the photocatalytic functional layer are covered with the photodegradation resistant matrix (thermosetting resin, etc.), the electron capturing metal effectively captures the electrons generated by the photocatalytic reaction, retains the holes and generates the active oxygen seed. Therefore, the photocatalytic function such as deodorizing and antimicrobial effects can be fully exhibited.
