Abstract: In one aspect, the present invention is an organic-inorganic hybrid membrane of a cerium oxide and an organic fluorine compound, the organic-inorganic hybrid membrane satisfying the following (a), (b), and (c): (a) the visible-light transmittance is 70% or higher; (b) the UV transmittance at a wavelength of 380 nm is 60% or lower; and (c) the water contact angle of the surface of the organic-inorganic hybrid membrane is 80° or higher. In another aspect, the present invention is an organic-inorganic hybrid membrane of a cerium oxide and an organic fluorine compound, the organic-inorganic hybrid membrane satisfying the following (a), (b), and (c?): (a) the visible-light transmittance is 70% or higher; (b) the UV transmittance at a wavelength of 380 nm is 60% or lower; and (c?) the water contact angle of the surface of the organic-inorganic hybrid membrane is 90° or higher. The organic fluorine compound may include a fluorine-based resin.
