An image reading apparatus includes a LED that emits white light, a light guiding body, and a photoelectric conversion element. The light guiding body is disposed along the main scanning direction. The light guiding body includes an incident surface, a plurality of groove portions, an emission surface, and a scattering portion. The incident surface is formed on one end in a longitudinal direction, faces the light emitting surface of the LED that emits white light, and receives incident light that is emitted from the light emitting surface. The plurality of groove portions is formed on the incident surface and is formed concentrically to the center of the incident surface. The emission surface is formed along the main scanning direction. The scattering portion scatters light and includes a plurality of prisms. The scattering portion is opposed to the light emitting surface and is disposed along the main scanning direction.
