PROBLEM TO BE SOLVED: To stick a reflector sheet to a reflector surface without producing distortion of a light reflecting surface. SOLUTION: In a scanner device for performing exposure scanning of an original image with light emitted toward contact glass from a light source disposed with a horizontal scanning direction as a longitudinal direction, a groove 19b extending from one end to the other end along the longitudinal direction of the reflector surface 19a facing the light source and the contact glass is formed, and in sticking the reflector sheet 20 to the reflector surface 19a, air between the reflector sheet 20 and the reflector surface 19a is pushed out through the groove 19b by sticking the reflector sheet 20 along the groove 19b formed along the longitudinal direction from one end side toward the other end side.
