Abstract

A light shielding member for an optical instrument has a reduced thickness and increased stiffness, which helps to further reduce the size and weight of high-performance single-lens reflex cameras, compact cameras, video cameras, etc. The light shielding member (3) has a base (1) constructed from at least two plastic films (11) and from an intermediate layer (12) with a curable resin placed between the at least two plastic films (11), and also has a light shielding film (2) formed on at least either surface of the base (1).
