Abstract
Provided is a light illuminating apparatus for irradiating light of a line shape extending in a first direction and having a line width in a second direction. The light illuminating apparatus includes light emitting units, each including a substrate, light sources arranged at an interval along the first direction on the substrate and placed such that a direction of an optical axis is matched to a direction perpendicular to the substrate surface, and optical devices placed on optical paths of each light source to shape light from each light source into light with a predetermined divergence angle, wherein the light emitting units are arranged on an arc having its center at the irradiation position when viewed in the first direction, and an irradiation width in the second direction of light from the light emitting units is approximately equal within a preset range in a direction perpendicular to the irradiation surface.
