Abstract: PROBLEM TO BE SOLVED: To suppress the warpage of a card due to embossing by a method wherein a lamination form, the density distribution to the direction of the thickness of inorganic flake-like filler satisfies the formulae I and II is taken. SOLUTION: In order to form a single layer sheet, a plurality of which compose a multilayer sheet, the loaidngs of an inorganic flake-like filler, the particle form of which is nonisotropic three-dimensionally and has a biaxial orientational property, is preferably 2-25 pts.wt. to 100 pts.wt. of 1 or 2 or more of thermoplastic resins selected from the group consisting of an amorphous polyester and an aromatic polycarbonate. In the multilayer sheet produced by laminating at least these two or three or more single layer sheets, when let the thickness of the multilayer sheet be 2L, the X-axis be in the direction of the thickness, the origin of the X-axis be the center of the multilayer sheet, the density of the inorganic flake-like filler at X be C(X), the single layer sheets are laminated in the form of the multilayer sheet, in which the resultant density distribution of the inorganic flake-like filler in the direction of the thickness satisfy the formulae I and II. In other words, the density distribution of the inorganic flake-like filler in the direction of the thickness is formed through such as laminating fashion that the density in the outer layer is made higher than that in the inner layer, resulting in remarkably improving the embossing characteristics of the multilayer sheet.
