Disclosed is a method and an apparatus are providednwhich can efficiently produce a functional material havingna satisfactory level of photocatalytic activity. Anphotocatalyst coating composition comprising anphotocatalytic metal oxide and/or a precursor of thenphotocatalytic metal oxide is coated on the surface of ansubstrate. The surface of the coated substrate is rapidlynheated to fix the photocatalytic metal oxide onto the surfacenof the substrate. This rapid heating can realize thenproduction of a functional material having a satisfactorynlevel of photocatalytic activity in an efficient manner. Thenapparatus, which can continuously carry out the rapid heatingnimmediately after the production of the substrate, cannproduce the functional material having photocatalyticnactivity in an efficient manner. |
