PROBLEM TO BE SOLVED: To provide an optical element placed horizontally, such as square lens, in which obliquely arrangement thereof is prevented while suppressing reduction in molding efficiency and increment in cost.SOLUTION: Since a gap from a second mold member 52 clamped in an opposing manner to a first mold member 51 is reduced by adjustment in thickness in central axis CX direction of a flange adjusting member 53 for forming a flange side surface (flat surface) 12e, even in a case where the side surface shape of an optical element 30 by contacting the pair of mold members 51, 52 is molded, it is prevented that the optical element 30 which should be placed horizontally is obliquely arranged due to burr extending beside from the side surface.SELECTED DRAWING: Figure 1 |
