Abstract: A light-shading member for an optical device which has excellent reflection preventing performance can be manufactured by a simple process and can be applied to an optical device which is small and thin. Based on JIS B0601: 2001, the arithmetical mean deviation of the assessed profile Ra of the surface of the light-shading member for an optical device is 0.5 μm or more, and the difference (Rp-Rv) between the maximum profile peak height Rp and the maximum profile valley depth Rv is less than 3. The light-shading member for an optical device preferably has a substrate film and a light-shading layer. The light-shading layer is formed on at least one surface of the substrate film. Further, the light-shading layer has an average film thickness of 2 μm-35 μm.
