A head-up display projects an image on a transparent reflective member to allow an observer to visually recognize a virtual image. The head-up display includes a display device and a projection optical system. The projection optical system includes a refractive optical system and a concave mirror. The display device displays the image. The projection optical system projects the image displayed on the display device to a visual point of an observer. The refractive optical system includes at least one optical element. The concave mirror has a concave reflection surface. The refractive optical system is positioned on an optical path between the display device and the concave mirror. In the refractive optical system, an incident surface of a lens element having negative power into which light of the image displayed on the display device is incident is concave.
