Abstract:
A liquid repellent structure includes a surface to which liquid repellency is to be imparted, and a liquid repellent layer formed on the surface. In the structure: the liquid repellent layer contains a binder resin containing a fluorine-containing resin, and a filler dispersed in the binder resin; the filler contains a first filler having a BET specific surface area M of 100 m2/g to 400 m2/g; and the ratio M/F of the BET specific surface area M of the first filler to a mass F (mass %) of the fluorine-containing resin relative to the total mass of the liquid repellent layer is 4.1 to 20.0.
