Claim 0:
1. A liquid-repellent structure, comprising:
a major surface to which liquid repellency is imparted, and
a liquid-repellent layer on the major surface; wherein
the liquid-repellent layer is a single layer;
the liquid-repellent layer contains a scale-like filler having an average particle size of 0.1 to 6 μm, inclusive, a thermoplastic resin, and a fluorine compound, and has aggregates containing the scale-like filler;
the thermoplastic resin is selected from the group consisting of low density polyethylene, medium density polyethylene, high density polyethylene, ethylene-α olefin copolymer, homo, block, or random polypropylene, propylene-α olefin copolymer, ethylene-vinyl acetate copolymer and an acid modified polyolefin,
the thermoplastic resin constitutes 50 mass % to 95 mass % of a combination of the thermoplastic resin and the fluorine compound, and
the ratio WS1/(WP+WFC) of the mass WS1 of the scale-like filler contained in the liquid-repellent layer to the sum (WP+WFC) of the mass WP of the thermoplastic resin and the mass WFC of the fluorine compound contained in the liquid-repellent layer is 0.1 to 10 inclusive.
