This decorative sheet (20) comprises: a substrate layer (1); a pattern layer (2) that is provided on the side of the first front surface (1a) of the substrate layer (1); and a thermoplastic resin layer (3) that is provided on the side of the second front surface (2a) of the pattern layer (2). When a test piece with a width of 8 mm is prepared from the decorative sheet (20) and the storage modulus is measured for the prepared test piece with an initial chuck distance of 10.77 mm, at a start temperature of 30°C, an end temperature of 150°C, a temperature increase rate of 5°C/min, and a measurement frequency of 1.0 Hz, the ratio of the difference between the second storage modulus and a third storage modulus when the decorative sheet (20) changes from the transition region to a rubbery flat region relative to the difference between a first storage modulus when the environmental temperature is 30°C and a second storage modulus when the decorative sheet (20) changes from a glassy region to a transition region is 3.5 or less.
