PROBLEM TO BE SOLVED: To provide a molding method of a sheetlike molded product capable of easily applying a difference in sticking degree to the sheetlike molded product between both upper and under surfaces thereof when the sheetlike molded product is subjected to extrusion molding using a rubber or an elastomer as a molding material. SOLUTION: In a method for applying a difference in sticking degree to the sheetlike molded product 5 between both upper and under surfaces thereof when the sheetlike molded product 5 is subjected to extrusion molding using the rubber or elastomer as the molding material, a temperature difference wherein the surface temperature of a roll 8 is higher than that of a roll 7 is set to a rolling roll 6 at the time of extrusion molding of the sheetlike molded product 5 to provide a difference between the transfer degrees of the surfaces of the rolls 7 and 8. By this method, a surface low in the transfer degree of the surface of the roll 7 and hard to stick and a surface high in the transfer degree of the surface of the roll 8 and easy to stick are molded on the sheetlike molded product 5.
