PROBLEM TO BE SOLVED: To provide a projector capable of avoiding a situation where it becomes difficult to control temperature of a plurality of light source units.SOLUTION: A head-up display device 100 (projector) of the present invention includes laser diodes 11a-11c, a housing unit 7 (base unit 7), and heat sinks 5a and 5b, where thermal resistance of a first heat transfer path from the laser diode 11a (or 11b or 11c) to the housing unit 7 is greater than that of a second heat transfer path from the laser diode 11a (or 11b or 11c) to the heat sink (5a or 5b).

    【課題】複数の光源部の温度調節が困難になるのを抑制することが可能なプロジェクタを提供する。【解決手段】このヘッドアップディスプレイ装置100(プロジェクタ)は、レーザダイオード11a〜11cと、ハウジング部7(基台部7)と、ヒートシンク5aおよび5bとを備え、レーザダイオード11a(11bまたは11c)からハウジング部7までの第1の伝熱経路の熱抵抗は、レーザダイオード11a(11bまたは11c)からヒートシンク5aまたは5bまでの第2の伝熱経路の熱抵抗よりも大きい。【選択図】図6
