Abstract
A light irradiation device includes: a light source configured to output light having coherence; a light focusing element having a focusing axis and a non-focusing axis intersecting with the focusing axis and configured to focus the light on a focusing line so as to generate planar light; and an aperture mask having an opening part that limits a part of luminous fluxes of the light transmitted from the light source to the light focusing element. The opening part of the aperture mask has opening edges disposed to extend in a direction along the focusing axis of the light focusing element, and, in a case in which the opening edges are projected onto the focusing line, corresponding projected portions have linear spreads.
