    • An object is to provide a laminated film, a film for protected horticulture, a woven or knitted fabric, and the like that suppress deterioration in appearance and yellowing of a film due to ultraviolet rays and maintain high light transmittance. A laminated film having a heat-ray reflection layer and a weather-resistant layer on at least one surface of the heat-ray reflection layer, in which the heat-ray reflection layer has a multilayer laminated structure in which 20 or more layers of a first layer mainly composed of a resin and a second layer mainly composed of a resin are alternately laminated in a thickness direction, the first layer contains polyethylene naphthalate, a protective layer is provided on at least one surface of the multilayer laminated structure, the protective layer has a thickness of 10 µm or less, the protective layer is a layer mainly composed of the resin of the first layer, the weather-resistant layer is composed of a resin composition containing an ultraviolet absorber having a triazine skeleton, and a content of the ultraviolet absorber in the weather-resistant layer is 8 to 45 mass%, the weather-resistant layer has a thickness of 3 to 15 um, and a secondary reflection band of the laminated film is 400 to 700 nm, and a spectral transmittance in the secondary reflection band is 60% or more.
