PROBLEM TO BE SOLVED: To provide a laminated sheet for manufacturing a can capable of reducing shaving-off of a film layer when the can is manufactured even though it contains pigment, having excellent corrosion resistance and hiding property due to increase of whiteness of the outer face, and in which print quality is improved, and a coated seamless can which is obtained by using this laminated sheet and has excellent impact resistance (dent resistance). SOLUTION: In this laminated sheet in which a resin film containing a surface resin layer (a) in which pigment content is 20 wt.% or less and a resin layer (b) in which the pigment content is 10-70 wt.% and is more than that of the surface resin layer (a) is laminated on a metal sheet, the resin layer (b) of the laminated sheet is a base layer, the value of birefringence (Δn) of a film part contacting to the metal sheet of the resin layer (b) is 0.1 or less and is the value of the birefringence of a film part on the front face side or less, provided that Δn=nm-nt, wherein nm is a reflective index in the maximum orientation direction of the film, and nt is the reflective index in a thickness direction of the film.
