A light-blocking member for optical instruments having improved abrasion resistance and adhesiveness while having high sliding properties and maintaining physical properties of a light-shielding layer, such as light-shielding properties and delustering properties, is provided. A light-blocking member for optical instruments can include a film substrate 2 and a light-shielding layer formed on at least one surface of the substrate. The light-shielding layer can include a binder resin, carbon black, a particulate lubricant and fine particles. Contents of the binder resin and particulate lubricant are 65 wt % or higher and 5 to 15 wt %, respectively. As the particulate lubricant, those having a higher density than that of the fine particles can be used. |
