PROBLEM TO BE SOLVED: To provide an image projection device that can reduce the size of the image projection device and satisfactorily cool a power source substrate.SOLUTION: An image projection device comprises: a control part that controls light emission of a light source 61; a power stabilization part for supplying a stable power to the light source 61; and a power supply unit 80 that supplies a power to at least one of the control part and the power stabilization part. One or both of the power supply unit 80 and the power stabilization part is (are) divided into a plurality of substrates (80a and 80b); the light source 61 is arranged on the normal of a surface of any one of the plurality of substrates (80a and 80b); the plurality of substrates (80a and 80b) form a channel not including at least a surface closest to the light source 61.SELECTED DRAWING: Figure 23 【課題】画像投影装置を小型化すること、また、電源基板を良好に冷却することができる画像投影装置を提供する。【解決手段】光源６１の発光を制御する制御部と、光源６１に安定した電力を供給するための電力安定部と、制御部および前記電力安定部の少なくともどちらか一方に電力を供給する電源ユニット８０とを備え、電源ユニット８０および電力安定部の一方もしくは両方を複数の基板（８０ａ、８０ｂ）に分割し、光源６１は複数の基板（８０ａ、８０ｂ）のいずれかの面の法線上に配置され、複数の基板（８０ａ、８０ｂ）は、少なくとも光源６１に最も近い面を備えない流路を形成する。【選択図】図２３
