PROBLEM TO BE SOLVED: To improve thickness accuracy and to reduce the coefficient of contraction. SOLUTION: When an embossed pattern is transferred to a resin 10 film extruded in a molten state from a mold 11 with cooling, the resin 10 is pressed between an embossing roll 12 and a receiving roll 15 to apply linear pressure, surface pressure is applied by an endless metal belt, the resin 10 is cooled, and an embossed pattern is transferred. |
