PROBLEM TO BE SOLVED: To provide an adhesive sheet including high ultraviolet light absorption and light diffusion effects.SOLUTION: An adhesive sheet includes a substrate layer, and an adhesive layer laminated on one side surface of the substrate layer and comprising the adhesive, wherein the adhesive layer includes an ultraviolet light absorber obtained by polymerizing a vinyl monomer having a benzotriazole skeleton and light diffusing particles, and the light diffusing particles include ≥60 mass% of light diffusing particles having a ≥0.1 μm and <6 μm particle diameter. The light-diffusing particles desirably include only light-diffusing particles having a ≥0.1 μm and <6 μm particle diameter; the light-diffusing particles are desirably silicone resin particles; their transmission factor to light of a 380 nm wavelength is desirably ≤3%, and the thickness of the adhesive layer is desirably ≥20 μm and ≤500 μm. |
