Abstract: A method for producing a decorative sheet includes the steps of: (α) pressing a thermoplastic resin film (a) on a preheated rotating heating drum, and then pressing a transfer film (b) having a hot-melt adhesive layer, a resin coating, a release coating layer, and a film base material in order such that the hot-melt adhesive layer is positioned in the film (a) side; (β) feeding/supplying a pressed body obtained in the Step (α) between a rotating design-imparting roll and a rotating receiving roll such that the transfer film (b) is positioned in the design-imparting-roll side; and (γ) sequentially passing a laminated sheet obtained in the Step (β) through a first chill roll whose temperature is set to 50° C. to 90° C., and a second chill roll whose temperature is set to a temperature of 20° C. to 70° C. which is lower than the first-chill roll temperature to cool the laminated sheet.
