Abstract: The invention aims to provide a substrate whose water-repellency is less likely to be deteriorated even after long-term use in an ultraviolet-exposure environment. The substrate of the invention includes a surface-treating layer, and exhibits a static contact angle with water of 100 degrees or greater after a 400-hour accelerated weathering test performed under the following conditions: preparing a UVB-313 lamp exhibiting an irradiance of 0.63 W/m2 at a wavelength of 310 nm; placing the surface-treating layer of the substrate apart from the lamp by 5 cm; and after every 24-hour irradiation, wiping the surface-treating layer with a cloth impregnated with water and with a cloth impregnated with ethanol, followed by drying.
