To provide a light shieldable film for optical apparatus which is lightweight and is excellent in performance, such as light shieldability, slipperiness, wear resistance, antistatic property arid flatness and is excellent in productivity as well.

This light shieldable film is formed by using a film essentially consisting of a thermoplastic resin for a base material film and providing both surfaces thereof with layers consisting of thermosetting resin contg. carbon black, lubricants and matting agents. The base material film is preferably a biaxially stretched polyethylene terephthalate film contg. the carbon black in order to improve the light shieldability. Polyurethane is used for the thermosetting resin layers. The carbon black having excellent colorability and the carbon black having excellent electrical conductivity are used for the carbon black to be included therein in such a manner that the mixing ratio thereof attains a range of 65/35 to 95/5. The layers are so constituted that the total carbon black as the amt. of the addition attains 40 to 70 pts.wt. per 100 pts.wt. total resin component.
