Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a light irradiation device capable of sufficiently cooling a light source part.SOLUTION: A light irradiation device comprises: a long light source part having a plurality of light emitting elements arranged side-by-side at the surface of a substrate installed along an opening for light irradiation inside a flat case formed with the opening for light irradiation at one end surface; and a heat sink arranged at a rear surface while being abutted against the rear surface of the substrate in the light source part. An inner side of the case is formed with a suction air flow passage where cooling air fed from the outside through a suction port formed at the case flows toward the heat sink. A suction air cooling fan is arranged at a position near the heat sink in the suction air flow passage. The suction port is formed at a peripheral surface other than one end surface and the other end surface opposing to each other at the case.SELECTED DRAWING: Figure 3 【課題】光源部を十分に冷却することのできる光照射装置を提供することにある。【解決手段】光照射装置は、一端面に光放射用開口が形成された扁平な筐体の内部に、当該光放射用開口に沿って設けられた、基板の表面に複数の発光素子が並設されてなる長尺な光源部と、当該光源部における基板の裏面側に、当該裏面に当接して配設されたヒートシンクとを備え、前記筐体の内部には、当該筐体に形成された吸気口を介して外部から導入される冷却風が前記ヒートシンクに向かって流動する吸気流路が形成され、当該吸気流路における当該ヒートシンクに近接した位置に、吸気用冷却ファンが設けられており、前記吸気口が、前記筐体における互いに対向する前記一端面および他端面以外の周面に形成されていることを特徴とする。【選択図】図３
