PROBLEM TO BE SOLVED: To provide a reflector capable of enhancing brightness of reflected light. SOLUTION: The reflector has a plenty of reflecting elements aligned in a nearly platy shape. If, out of virtual six plane surfaces making a regular hexagon, three plane surfaces neighboring each other are made as a first reference surface, a second reference surface, and a third reference surface, respectively, the reflecting element includes a first mirror face along the first reference surface, a second mirror face along the second reference surface, and a third mirror face along the third reference surface. When the first mirror face is formed in a curvature swelling outward against the first reference surface, the second mirror face is formed in a curvature swelling inward against the second reference surface, and moreover the third mirror face is formed in a curvature swelling inward against the third reference surface. When the first mirror face is formed in a curvature swelling inside against the first reference surface, the second mirror face is formed in a curvature swelling outward to the second reference surface, and the third mirror face is formed in a curvature swelling outward to the third reference surface.
