Abstract

A method for manufacturing a laminate sheet including a fluororesin film and a silicone rubber sheet that are adhered to one another, where the fluororesin film has a reactive functional group as a result of a surface treatment, the side with the reactive functional group is overlapped with an organic peroxide-containing millable-type silicone rubber composition, where the silicone rubber composition is sheet-shaped and the organic peroxide has a one-minute half-life temperature in the range of 100−150° C., and the silicone rubber composition is cured by being heated under pressure at 90-135° C. The laminate sheet has a peel adhesion strength of 3N or more. The four corners of a 120 mm square test sample of the laminate sheet do not curve into one end of a semicircular arc shape or one end of a C shape, and the average warpage value of the four corners is 35 mm or less.
