PROBLEM TO BE SOLVED: To form a composite molded lens in which adhesiveness of a joined surface is enhanced in molding the composite molded lens having a frame body thicker than an outer peripheral part of a lens part by continuously carrying out compression molding and injection molding.SOLUTION: In a composite molded lens 10, a lens body 11 formed of a lens part 12 and a first flange part 13 formed so as to surround the lens part 12 is compression-molded. Then, resin such as PMMA and PC is injected, and a frame body 14, which is formed of a frame part 15 formed so as to surround the first flange part 13, and a second flange part 16 integrally formed on an inner diameter side of the frame part 15 and adjacent in an optical axis direction of the first flange part 13, is formed. The second flange part 16 is tightly joined to the first flange part 13 and is solidly joined by injection molding. An outer peripheral end surface 18 of the first flange part 13 is crushed until it protrudes in a frame part forming space to form a joined surface with the frame part 15. |
