英文摘要	The objective of the present invention is to efficiently dissipate heat generated by a plurality of light sources which generate light having different wavelengths. This head-up display device is provided with: a combined light output unit (10) which outputs combined light obtained by combining light emitted by a plurality of light sources (11) which emit light having different wavelengths; and a heat dissipator (15) which dissipates heat emitted by the light sources (11). The head-up display device displays a virtual image by means of the combined light. The plurality of light sources (11) include a first light source (11a) which operates in a first operation guaranteed temperature band, and second light sources (11b, 11c) which operate in a second operation guaranteed temperature band having an upper limit higher than that of the first operation guaranteed temperature band. The first light source (11a) is provided in a location (15a) on the heat dissipator (15) having a higher heat dissipation characteristic than the locations of the second light sources (11b, 11c).
