A reading module has a light source, an optical system having a mirror array and an aperture stop portion, a sensor in which a plurality of image regions where the image light is converted into an electrical signal are arranged; a housing; and a light-shielding wall shielding stray light striking the image regions. In the mirror array, a plurality of reflective mirrors whose reflection surfaces are aspherical concave surfaces are coupled together in an array in the main scanning direction. The optical system is fixed to on the case housing at one point in the main scanning direction, and the light shielding walls are arranged at a positions displaced deviated by a predetermined amount from boundaries between the image regions in the direction opposite to the fixed side of the optical system.
