Patent ID: 8288708

Claim:
An optical filter disposed on an image sensor including a plurality of sensor pixels aligned, comprising: an elongated translucent substrate; a first optical filter layer laminated on the translucent substrate; and a second optical filter layer laminated on the first optical filter layer, wherein the translucent substrate includes: a photodetecting part which is long in the alignment direction of the plurality of sensor pixels and positioned immediately above the image sensor; and a frame part surrounding the photodetecting part, the photodetecting part includes: a light transmitting region positioned on one side in the longitudinal direction of the photodetecting part; a first filter region adjacent to the light transmitting region in the longitudinal direction of the photodetecting part; and a second filter region which is adjacent to the first filter region in the longitudinal direction of the photodetecting part and positioned on the side opposite to the light transmitting region across the first filter region, the first optical filter layer is laminated so as to cover the first filter region, the second filter region, and the frame part, and the second optical filter layer is laminated so as to cover the second filter region and the frame part.
