PROBLEM TO BE SOLVED: To enhance a read image by reducing the illumination fluctuation on the read area. SOLUTION: This image reader provided with a case 1, a plurality of light sources 6 arranged in a column shape in the case 1, a plurality of wall surfaces 15a to 15c which define an optical path 14 for illumination that makes light emitted from the plurality of light sources 6 proceed toward a linear read area S in the case 1 and enable the light to be reflected and a lens array 3 which is for forming the image of an original D arranged in the read area S on a plurality of photodetectors 7, is provided with a light shade 16 preventing the light from directly proceeding toward the area S from each of the light sources 6. A hole part 17 filled up with an adhesive 39 is provided in the case 1 as a means fixing the array 3, and is prevented from being open toward the optical path 14.
