Abstract: A water-repellent structure includes a substrate, and a water-repellent film formed on a surface of the substrate, in which: the water-repellent film includes a water-repellent layer containing a siloxane bond and one or more type(s) of organic groups bonded to a Si atom and not containing any fluorine atom; a surface of the water-repellent layer is an outermost surface of the water-repellent film; the surface of the water-repellent layer has an elastic modulus distribution, and includes a high elastic modulus part having an elastic modulus of 6.0 GPa or higher and a low elastic modulus part having an elastic modulus of 4.0 GPa or lower in an arbitrarily selected micron region of 1 μm square; and a root mean square inclination value of a surface elastic modulus in the micron region is 3.5 GPa or higher.
