摘要： Provided is a laminate that generates a structural color, where the laminate can be subjected to a deep-drawing process without deteriorating the color developing structure of the structural color. The laminate according to an embodiment of the present invention includes a polyamide layer (1) and a thermoplastic polyurethane layer (2) having a color developing structure of a structural color. The thermoplastic polyurethane layer (2) is preferably a thermoplastic polyurethane layer having a structure having recesses and protrusions on a face that is opposite a face in contact with the polyamide layer (1) or a layer formed by alternately laminating two types of thermoplastic polyurethanes having a difference in refractive indexes of 0.03 or greater.
