PROBLEM TO BE SOLVED: To provide a light shielding blade which is light in weight and has high rigidity, is inexpensive without lowering performance and has little possibility that it causes trouble in future even in terms of supply of material. SOLUTION: The light shielding blade 50 is constituted so that an aramid fiber reinforced resin layer 54 is arranged in the center in a thickness direction, and glass fiber reinforced resin layers 52 and 52 and light shielding resin layers 56 and 56 are successively formed on the front and back principal surfaces of the aramid fiber reinforced resin layer 54. The glass fiber reinforced resin layer 52 contains glass fibers in the form where the arrays of fiber cross each other. COPYRIGHT: (C)2009,JPO&INPIT
