To provide a light source device which can uniformize temperatures of multiple light emitting elements.SOLUTION: A light source device 100 includes: a housing 10 which is elongated in an X direction; multiple LED elements 31 disposed within the housing 10 and arranged along at least the X direction; and multiple heat sinks 50 disposed within the housing 10 and thermally connected with the LED elements 31. A first suction port 11 which suctions air from the outside into the housing 10 is provided on one end surface 10a at one side of the housing 10 as seen in the X direction. An exhaust port 13 which exhausts air from the interior of the housing 10 to the outside is provided on the other end surface 10b at the other side of the housing 10 as seen in the X direction. The housing 10 is formed with spaces 1 in which the other side as seen in the X direction faces the heat sinks 50. Second suction ports 2 which suction air from the outside into the spaces 1 are provided on side surfaces 22a, 23a between the first suction port 11 and the exhaust port 13 in the housing 10.SELECTED DRAWING: Figure 5 【課題】複数の発光素子の温度を均一化できる光源装置を提供する。【解決手段】光源装置１００は、Ｘ方向に長尺状の筐体１０と、筐体１０内に配置され少なくともＸ方向に沿って並ぶ複数のＬＥＤ素子３１と、筐体１０内に配置されＬＥＤ素子３１と熱的に接続された複数のヒートシンク５０と、を備える。筐体１０におけるＸ方向の一方側の一端面１０ａには、外部から筐体１０内にエアを吸い込む第１吸気口１１が設けられている。筐体１０におけるＸ方向の他方側の他端面１０ｂには、筐体１０内から外部へエアを排出する排気口１３が設けられている。筐体１０内には、Ｘ方向の他方側がヒートシンク５０に面する空間１が形成されている。筐体１０における第１吸気口１１と排気口１３との間の側面２２ａ，２３ａには、外部から空間１にエアを吸い込む第２吸気口２が設けられている。【選択図】図５
