Abstract
A filter includes resin particles and photocatalyst particles having absorption at wavelengths of 450 nm and 750 nm in the visible absorption spectrum. The photocatalyst particles have a high photocatalytic function and are present on the surface of the resin particle. The filter is air permeable, transmits visible light, and has high deodorizing performance.
