To obtain such a releasing sheet for press forming that is provided with releasability and cushioning property and that is superior in dimensional stability and durability by interposing a fluororubber coated layer between plural base materials and providing a releasing layer on the surface of the base material.
An unvulcanized fluororubber solution is applied on either one or both of the oppositely facing surfaces of base material layers 2 and dried to form an unvulcanized fluororubber layer 3. Then, the base material layers 2 are laminated, with a releasing layer 4 provided on the surface side of the base material 2 situated on the uppermost and the lowermost position. The laminated base material is heated and pressurized, with the unvulcanized fluororubber layer 3 vulcanized, and with the entirety adhesively uniformized to form a releasing sheet for press forming. The base material layer 2 is desirably an inorganic material with a thermal conductivity of 0.6W/m.K or above. The thickness of the fluororubber coated layer 3 is desirably in the range of 20-200μm. For the releasing layer 4, a heat resistant releasing paint or film is used. This releasing sheet is superior in heat conductivity and capable of uniformizing the variance of temperature transmitted within the plane.
