Abstract
A substrate is formed in a rectangular shape, a plurality of light emitting elements are arranged on one end face of the substrate, and a translucent sealing material is adhered to the one end face to seal the light emitting elements. A light irradiation device is thin, which transfers heat generated at the light emitting elements to the substrate where the heat is dissipated. Even if the substrate is made thinner, the heat dissipation performance of the substrate can be maintained or enhanced when the dimension of the substrate is increased in the direction intersecting the one end face of the substrate.
