A light−reflecting sheet (1) which comprises a laminate (10) having a white pigment containing layer (8) having, on the surface thereof, projections (7) having an average height of 0.1 to 5 μm and a polymer layer (9) laminated on the projection (7) side of the white pigment containing layer (8). The light−reflecting sheet is free from inconsistencies in brightness, is less prone to the appearance of a white spot, and does not cause interference fringes due to the sticking thereof or the like. Une feuille réfléchissant la lumière (1) comprend une partie stratifiée (10) possédant une couche (8) contenant un pigment blanc. A sa surface, on a formé des protubérances (7) ayant une hauteur moyenne de 0,1 à 5 mu m et une couche polymère (9) stratifiée sur le côté des protubérances (7) de la couche (8) contenant un pigment blanc. La feuille reflétant la lumière est exempte de toute solution de continuité en termes de brillance, présente moins de risques d'apparition d'une tache blanche et ne provoque aucune frange d'interférence suite au collage ou similaire.
