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 cmto a peak intensity of an absorption at about 1037 cmbeing 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 cmand not more than 1700 cmto a peak intensity of an absorption at about 1037 cmbeing 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 cmand not more than 5400 cmor a ratio of a maximum peak intensity of an absorption to an absorption intensity at 5250 cmbeing 1.7 or less in the analysis.
