Abstract
According to one embodiment, a photocatalyst body satisfies at least one condition described below, (1) a ratio of an absorption intensity at a wave number of 3450 cm−1 to a peak intensity of an absorption at about 1037 cm−1 being 2.5 or less in an analysis of a surface of the body, (2) a ratio of a maximum peak intensity of an absorption in a wave number range of not less than 1500 cm−1 and not more than 1700 cm−1 to a peak intensity of an absorption at about 1037 cm−1 being 0.7 or less in the analysis and (3) the photocatalyst body having no absorption peak in a wave number range of not less than 5000 cm−1 and not more than 5400 cm−1 or a ratio of a maximum peak intensity of an absorption to an absorption intensity at 5250 cm−1 being 1.7 or less in the analysis.
