PROBLEM TO BE SOLVED: To provide an image reading unit which obtains excellent images. SOLUTION: The image reading unit is provided with: a xenon lamp; a frame 601 having first and second side walls 60a (60b); a reflection unit for reflecting light reflected on an original; a lens unit for forming an image from the light reflected on the reflection unit; an image sensor for converting the light forming the image in the lens unit to electric signals; first and second supporting plates 750a (750b) disposed on the outer side of the first and second side walls 60a (60b) for supporting the reflection unit; and leaf springs 860 and 861 for energizing the reflection unit to the side of the first and second plates 750a (750b). The irregular reflection of the light generated through the first and second supporting plates 750a (750b) is reduced and the change of the position of the reflection unit due to the thermal expansion of the first and second supporting plates 750a (750b) is suppressed.
