PROBLEM TO BE SOLVED: To integrally form a metal frame with high rigidity, the inner periphery of which is tapered and an optical element. SOLUTION: In the optical component 40, the optical element 33 having a larger wall thickness in the outer peripheral part than in the center of optical axis (O-O) and the metal frame 24 are integrally formed. In the optical component, a tapered part 26 inclined to the optical axis (O-O) is formed on the inner periphery of the metal frame 24. COPYRIGHT: (C)2009,JPO&INPIT
