<p><P>PROBLEM TO BE SOLVED: To provide a compact imaging apparatus which has an optical low-pass filter provided with excellent environmental resistance and assembling operability. <P>SOLUTION: The optical filter which attenuates high frequency components of a light flux from a taking lens and removes infrared wavelength components of the light flux includes a first optical member 300 and a second optical member 302, and the second optical member 302 is attached to a filmed resin filter 301. The first optical member 300 is pressed and held to a filter holding member 303 through an elastic member 306, and the second optical member 302, the front of which is faced to the first optical member 300, is fixed to the filter holding member 303, so that the filmed resin filter 301 is placed between the first optical member 300 and the second optical member 302. Thereby, the filmed resin filter 301 is not exposed to the outside and problems related to environmental resistance can be solved. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
