| description | PROBLEM TO BE SOLVED: To highly accurately read a document (illuminated object) by reducing an illuminance deviation not only in a main scanning direction but also in a sub scanning direction of the document (illuminated object) in a transmission image sensor. SOLUTION: An image sensor of the present invention comprises a plurality of light sources 3 arrayed in the main scanning direction, a lens array 13 for converging light of the light sources 3 transmitted through an illuminated object 1, a sensor 14 for detecting light through the lens array 13, and a lightguide 4 which is disposed between the light sources 3 and the illuminated object 1 and includes an incidence plane 4b of which a surface is made coarse to scatter light from the light sources 3, and an emission plane 4a in which uneven portions are provided on its surface in the main scanning direction to diffract light in the main scanning direction and to emit the light toward the illuminated object.
