Abstract
An optical filteris disposed on an image sensorincluding a plurality of sensor pixelswhich are aligned, and includes a elongated translucent substrate; a first optical filter layerlaminated on the translucent substrate, and a second optical filter layerlaminated on the first optical filter layer. The translucent substrateincludes a photodetecting partwhich is long in the alignment direction X of the sensor pixelsand disposed on the image sensor; and a frame partsurrounding the photodetecting part. The photodetecting partincludes a light transmitting regionon one side in the longitudinal direction of the photodetecting part; a first filter regionadjacent to the light transmitting regionin the longitudinal direction of the photodetecting part, and a second filter regionwhich is adjacent to the first filter regionin the longitudinal direction of the photodetecting partand disposed on the side opposite to the light transmitting regionacross the first filter region. The first optical filter layercovers the first and second filter regionsandand the frame part, and the second optical filter layercovers the second filter regionand the frame part
