    Abstract: A decorative sheet for injection-molding and decorating a resin simultaneously, the decorative sheet containing two resin sheets laminated on each other with at least one patterned layer intervening therebetween, and the two resin sheets having a difference in linear expansion coefficient of 4×10?5/° C. (41 to 50° C.) or less. Even after subjecting to three-dimensional processing, such as vacuum molding, the decorative sheet suffers no warpage, and can be easily released from a mold for the three-dimensional processing, and even when the decorative sheet is set in a mold for injection molding, the decorative sheet does not fall off from the mold, a resin injected does not permeate a gap between the outer surface of the decorative sheet and the mold, and the decorative sheet suffers no peeling between the sheets constituting the decorative sheet.
