To provide a reflector which has high directivity and can achieve high luminance, and to provide a head-up display and a vehicle equipped with the head-up display.SOLUTION: A reflector according an embodiment includes: incident openings 46b; emission openings 46b at the opposite side of the incident openings; and reflection surfaces 48 each extending from the incident opening to the emission opening. The emission opening has a rectangular shape having four sides including two sides facing each other in a first direction and two sides facing each other in a second direction. The incident opening has a rectangular shape having four sides including two sides facing each other in the first direction and two sides facing with each other in the second direction. The reflection surface includes four reflection surfaces each having a curve surface extending from one side of the emission opening to one side of the incident opening. Curvature radii of the two reflection surfaces facing each other in the first direction are different from curvature radii of the two reflection surfaces facing each other in the second direction.SELECTED DRAWING: Figure 4A

    【課題】実施形態の課題は、高い指向性を有し高輝度化が可能なリフレクタ、ヘッドアップディスプレイ、およびヘッドアップディスプレイを搭載した車両を提供することにある。【解決手段】実施形態に係るリフレクタは、入射開口46bと、入射開口と反対側の出射開口46aと、入射開口から出射開口まで延在する反射面48と、を備えている。出射開口は、第1方向に対向する2辺と第2方向に対向する2辺の4辺を有する矩形状を有し、入射開口は、第1方向に対向する2辺と第2方向に対向する2辺の4辺を有する矩形状を有している。反射面は、それぞれ出射開口の1辺から入射開口の1辺まで延在する曲面を有する4面の反射面を含み、第1方向に対向する2つの反射面の曲率半径は、第2方向に対向する2つの反射面の曲率半径と異なる。【選択図】 図4A
