<P>PROBLEM TO BE SOLVED: To prevent deformation of an optical filter when being mounted. <P>SOLUTION: In a structure for mounting an optical filter 6 on another member 2 with an elastic member 7 sandwiched between peripheries and pressurized, the elastic member 7 is formed to have a cross-sectional shape such that an outer peripheral side part is extended toward the outside by application of pressure relative to an inner peripheral side part. Particularly, in a non-pressurized state, the inner peripheral side part of the elastic member 7 is in contact with the optical filter 6 and an outer peripheral side end part 71 of the elastic member 7 is separated from the optical filter 6. The outer peripheral side end part 71 of the elastic member 7 is formed to have a jagged shape, thereby the outer peripheral side end part 71 is in contact with the optical filter 6 by application of pressure and functions as an antiskid member toward the outside. In addition, the optical filter 6 is a plastic IR cut filter, and the another member 2 is an imaging element. <P>COPYRIGHT: (C)2012,JPO&INPIT |
