To obtain a light irradiation device for photocurable resin comprising a mechanism for making light for curing photocurable resin hardly exposed to a human body.SOLUTION: A light irradiation device for photocurable resin comprises: a body part comprising, on its undersurface side, a light source for radiating light for curing photocurable resin; and support means for supporting the body part. The body part is a frame having a rectangular outer shape and has, as the support means, four tabular leg parts erected at marginal parts of four sides of the body part so as to surround a lower space of the body part. The tabular leg parts reduce or intercept light from the light source in its whole wavelength region or a specific wavelength region.SELECTED DRAWING: Figure 1 【課題】 光硬化樹脂を硬化させる光が人体に暴露されにくい機構を備えた光硬化樹脂用光照射装置を得る。【解決手段】 下面側に光硬化樹脂を硬化させる光を照射する光源を備えた本体部と、本体部を支持する支持手段とを備えた光硬化樹脂用光照射装置において、本体部は外形が矩形状の筐体であり、支持手段として本体部の矩形の４辺の縁部に前記本体部の下部空間を囲むように立脚される４枚の板状の脚部を備え、板状の脚部が光源からの照射光の全波長領域又は特定波長領域を低減又は遮蔽するもの。【選択図】 図１
