PROBLEM TO BE SOLVED: To provide a lighting cover which is lighter than existing lighting covers made of milky glass or opal glass, has milky glass or opal glass tone appearance and texture with high-class feeling, and has high light transmittance, and to provide its manufacturing method. SOLUTION: In this lighting cover, a laminate 1 comprises a light diffusing layer 2 composed of resin composition where a light diffusing agent contained is 0.5 parts by weight or more and 40 parts by weight or less against 100 parts by weight of transparent resin, a transparent resin layer 3 composed of transparent resin, and a matting layer 4 containing the light diffusing agent. In the relative arrangement of each layer, the light diffusing layer 2 is arranged on the nearest side to an illumination source, and then the transparent resin layer 3 and the matting layer 4 are arranged in this order so as to be away from the illumination source, and thus the transmission and diffusion of light emitting from the illumination source are controlled.
