Claim Text:
1. A method for manufacturing a hydrophilic member, comprising: mixing at least one kind of particles selected from the group consisting of tungsten oxide particles each having a crystal structure and tungsten oxide composite particles each having a crystal structure, with an aqueous dispersion medium including at least one selected from the group consisting of water and alcohol, to obtain a dispersion liquid containing the particles and the aqueous dispersion medium, the crystal structure of the particles including a mixture of monoclinic crystal and triclinic crystal of tungsten trioxide; applying the dispersion liquid on a surface of a substrate; and drying the dispersion liquid applied on the surface of the substrate, without firing after drying, to form a dried film containing the particles and having a surface of which an arithmetic mean roughness Ra with a reference length of 100 μm is from 1 nm to 1000 nm, wherein the particles in the dried film exist on the surface of the substrate in a state that a crystal direction is not oriented, and wherein the dried film exhibits hydrophilicity independently of light based on the particles in the dried film, and a contact angle with water of the dried film stored for a month in a dark place and tested without light irradiation is 10° or less.
