A head-up display unit produces a first image representing first information and a second image representing second information floating in space by projecting light, emitted from a light source, toward a transparent projection member. The head-up display unit includes a first image generator and a second image generator. The first image generator has a first light transmission portion corresponding to the first image and generates a first image light, for producing the first image, by causing the light emitted from the light source to be transmitted through the first light transmission portion in a first direction. The second image generator is arranged parallel to the first image generator in a second direction crossing the first direction. The second image generator generates and outputs a second image light, for producing the second image, in a third direction along the first direction.
