PROBLEM TO BE SOLVED: To obtain a general-purpose photocatalytically functional body having a wide use end capable of retaining its sterilizing power and deodorizing power over a long time. SOLUTION: When the photocatalytically functional body 2 is formed by low temperature thermal spraying, conditions are set so as to obtain a photocatalytic film consisting of 10-40 wt.% anatase type crystals of titania and 60-90 wt.% rutile type crystals of titania. In the case of a coating film or printing ink, 50-80 wt.% rutile type fine grains of titania, 20-50 wt.% anatase type fine grains of titania, fine metal particles and fine ceramic particles as an adsorbent are mixed in a binder and stuck on a substrate 1 to form the objective body. |
