The present invention relates to a method for producing a laminated sheet comprising a fluororesin film and a silicone rubber sheet, wherein the method is characterized in that a fluororesin film having a reactive functional group subjected to surface treatment is superposed on a sheet-like organic peroxide-containing kneaded silicone rubber composition having a 1-minute half-life temperature in the range of 100 to 150 ℃, and the silicone rubber composition is cured by heating the mixture at 90 to 135 ℃ under pressure. The laminated sheet produced by the method comprises a fluororesin film and a silicone rubber sheet, wherein the fluororesin film is bonded to the silicone rubber sheet, the peel adhesion strength is 3N or more according to JIS K6854-2 (adhesive-peel adhesion strength test method-part 2: 180 degree peel), the four corners of the 120mm square laminated sheet are not bent into a shape having one end in the shape of a semicircular arc or a shape having one end in the shape of a C-letter, and the average warping value of the four corners is 35mm or less. |
