Zusammenfassung:PROBLEM TO BE SOLVED: To provide a composite material of a substrate and lens-shaped particles capable of preventing background reflections of light sources and having an excellent smoothness in terms of surface unevenness.SOLUTION: The provided composite material is a composite material comprising a substrate and lens-shaped particles configured on at least one surface of the substrate wherein the average height and average diameter of the lens-shaped particles are confined respectively to 1 μm to 100 μm and 1 μm to 1000 μm. In the composite material of the present invention, furthermore, it is desirable for the ratio of the occupant area of the lens-shaped particles atop the substrate surface where the lens-shaped particles are configured with respect to the area of the substrate surface to be 10-100%.
