Abstract:
PROBLEM TO BE SOLVED: To easily prevent an adhesive from penetrating to an exposure aperture on the contact surface of a plate filter member for adjusting light quantity with a plate filter supporting member having an aperture by a capillary phenomenon in a member obtained by sticking the filter member to the filter supporting member with the adhesive.
SOLUTION: The filter for adjusting the light quantity stuck to the filter supporting member with the adhesive is arranged at the innermost part of the recessed aperture part of the filter supporting member and connected to the sticking part in nearly V-shape or in nearly U-shape along the recessed shape of the aperture part at a position at a specified distance from both side parts, whereby the penetrating path of the adhesive is made longer so as to facilitate the prevention of the penetration of the adhesive to the exposure aperture.
