Abstract

In one embodiment, a hydrophilic member includes a substrate having a surface and particles existing at least on the surface of the substrate. The particles are constituted of at least one selected from tungsten oxide particles and tungsten oxide composite particles. The substrate surface on which the particles exist has an arithmetic mean roughness Ra in the range of 1 nm to 1000 nm with a reference length of 100 μm, and exhibits hydrophilicity independently of light.
