PROBLEM TO BE SOLVED: To provide a sheet-like laminated structure having excellent aesthetic properties and design properties and having a plurality of layers formed of a thermoplastic resin having a change of a continued color tone. SOLUTION: The sheet-like laminated structure comprises (1) at least two types of layers formed of the thermoplastic resin, (2) the laminated structure formed of a transparent resin containing a dye or a pigment in one layer, having a simple change of a thickness in at least one direction of the sheet surface, and other layer formed of a substantially colorless transparent resin or a transparent resin containing the dye or the pigment having a color different from that of the layer, (3) the entire laminated structure having a transparency, (4) the laminated structure recognized in a change of the continued color tone along the sheet surface when visually observed from an outside surface of the layer (B) formed of the transparent resin, and a character or a graphical form of a stereoscopic pattern in a boundary brought into contact with two types of the layers so that all the layers are formed of injection molding.
