To provide a light irradiation device capable of suppressing a deviation in the illuminance distribution of an irradiation light in order to solve the problem with a conventional light irradiation device for irradiating a light onto photocurable resin from a viewpoint of suppressing a deviation in the illuminance distribution of an irradiation light.SOLUTION: A light irradiation device 100 includes a light source part 20, and a light guide part 8. The light source part 20 outputs a light 26. The light guide part 8 guides the light 26 from the light guide part 20 by internally reflecting it, and emits it from an emission port 18h. In the light guide part 8, the inner shape of a cross section perpendicular to a light path is polygonal.SELECTED DRAWING: Figure 3 【課題】光硬化性樹脂に光を照射する光照射装置には照射光の照度分布の偏りを抑制する観点で改善すべき課題がある。本発明の目的は、このような課題に鑑みてなされたもので、照射光の照度分布の偏りを抑制することが可能な光照射装置を提供することにある。【解決手段】光照射装置１００は、光源部２０と、導光部８と、を備える。光源部２０は光２６を出力する。導光部８は光源部２０からの光２６を内面反射して導光し、出射口１８ｈから出射する。導光部８は、光路に対して垂直な断面の内形形状が多角形である。【選択図】図３
