<p><P>PROBLEM TO BE SOLVED: To make optical characteristics excellent by preventing deviation and tilt of a lens optical axis C relative to a diaphragm aperture of a lens barrel and the center thereof. <P>SOLUTION: In the optical element module, an upper first lens 406 and a lower second lens 407 are housed in a light-shielding holder 402, and a light-shielding plate 410 made of metal is interposed between at least respective flat surfaces of a spacer part 406D of the upper first lens 406 and a spacer part 407D of the lower second lens 407. The light-shielding plate 410 made of metal has an aperture 411a formed at a position corresponding to an optical surface of an optical element, and has a notched part 411e obtained by notching a portion of an outer circumferential edge of the light-shielding plate 410. Thus, since the light-shielding plate 410 is made of metal, it can be constituted to be thinner, whereby the optical characteristic is made to be excellent by suppressing variation of space between the lenses further. Since the light-shielding plate 410 has the notched part 411e obtained by notching a portion of the outer circumferential edge of the light-shielding plate 410, cut area is reduced, whereby more satisfactory cutting is performed in cutting in a lump. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
