Abstract: Resin particles include mother particles containing a biodegradable resin, in which an alkali metal atomic weight A present on a resin particle surface with respect to a total atomic weight present on the resin particle surface, which is measured by an X-ray photoelectron spectroscopy, and an alkali metal atomic weight B present in the resin particles with respect to the total atomic weight present on the resin particles, which is measured by a fluorescent X-ray spectroscopy, satisfy a relationship of 0≤(A/B)

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.

Abstract: A water purification member includes a porous body; and photocatalyst particles loaded on the porous body and including titanium-based compound particles that have, via an oxygen atom, a surface-bonded metallic compound having a metal atom and a hydrocarbon group, that exhibit absorption at a wavelength of 500 nm in a visible absorption spectrum, and that have an absorption peak in a range of 2700 cm−1 to 3000 cm−1 in an infrared absorption spectrum.
