<p>Disclosed is a hydrophilic material which, while maintaining satisfactory layer hardness and endurance properties, is less likely to fog and, at the same time, is less likely to cause the deposition of water droplets and soils or stains thereon. The hydrophilic material according to the first aspect of the present invention comprises at least a substrate and a hydrophilic layer provided as the outermost layer on the substrate, the hydrophilic layer comprising at least hydrophilic metal oxide particles and a hydrophilic inorganic amorphous material, the hydrophilic layer having on its surface profile peaks, the hydrophilic layer having roughness properties such that, when a segment is set in only a portion not containing the profile peaks, the ten-point mean roughness (Rz) and the mean distance between concaves and convexes (Sm) obtained from a profile curve in the segment are 10 nm≤Rz≤40 nm and 10 nm≤Sm≤300 nm, respectively, while, when a segment is set so as to pass through the profile peaks, the ten-point mean roughness (Rz) and the mean distance between concaves and convexes (Sm) obtained from a profile curve in the segment are 40 nm≤Rz≤200 nm and 300 nm≤Sm≤1500 nm, respectively. The hydrophilic material according to the second aspect of the present invention comprises at least a substrate, a first hydrophilic layer provided on the substrate and consisting essentially of a hydrophilic inorganic amorphous material and hydrophilic metal oxide particles, and a second hydrophilic layer provided as the outermost layer on the first hydrophilic layer and consisting essentially of a hydrophilic inorganic amorphous material.</p> |
