<P>PROBLEM TO BE SOLVED: To reduce degradation of image quality by ghost light caused between an infrared cut filter and an imaging element. <P>SOLUTION: A light absorption structure 4 for absorbing light of an infrared half value wavelength of an infrared cut filter 1 is disposed on a surface opposed to an imaging element 5. Thus, light transmitted through the filter 1 and reflected by the imaging element 5 is transmitted through the light absorption structure 4 before reaching a near infrared reflection structure 3 of the filter 1, so that reflection light by the reflection structure 3 can be reduced. The reflection light reflected by the imaging element 5 and reflected by the reflection structure 3 is transmitted through the light absorption structure 4 again before reaching the imaging element 5, so that reflectance by incident light from the imaging element 5 can be reduced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
