The thermoplastic resin film 5 extruded from the T-die 4 is superimposed just before the pressing surface between the pressure roll 3 and the cooling opening roll 2, and the cooling roll 2 has a fine uneven pattern on the entire circumference. At the same time as the thermoplastic resin film 5 is cooled, the thermoplastic resin film 5 and the base material 6 are pressed and laminated using the pressure roll 3, and at this time, the inverted pattern of the fine unevenness pattern on the entire circumference of the cooling roll 2 is made of thermoplastic resin. The thermoplastic resin film 5 is formed on the resin film 5 and the base material 6 surface, and the thermoplastic resin film 5 retains the uneven pattern formed on the base material 6 surface, forms a release paper 7, and is released from the roll coater part l. As the base material 6 of the paper pattern 7, materials used as usual base materials for release paper can be used, such as paper, plastic film, synthetic paper, or composites thereof.
