Abstract: Disclosed is a photocatalyst member including a glaze layer and a photocatalyst layer provided on the glaze layer, the photocatalyst layer is good in layer strength, water resistance, or abrasion resistance. More specifically, the photocatalyst member includes a base having a glaze layer and a photocatalyst layer that is provided on the glaze layer and contains titanium oxide and zirconium titanate, wherein the content of zirconium titanate in the photocatalyst layer is 15 to 75% by mass based on the total content of titanium oxide and zirconium titanate, and the content of zirconium titanate in an area from around an interface between the photocatalyst layer and the base to an median line in the thickness of the photocatalyst layer is larger than the content of zirconium titanate in an area near the external surface of the photocatalyst layer.
