Abstract:
A fluorocarbon resin sheet having a fluorine content of at least 55 wt. % and a melting point of from 60 to 220.degree. C., made solely of a polymer comprising at least one fluorine-containing monomer, or made of a blend of such a polymer with other polymer, which has a total light transmittance of at least 80% and a tensile modulus of elasticity within a range of from 1.times.10.sup.7 to 4.times.10.sup.9 Pa within an entire measuring temperature range of from 0 to 30.degree. C., wherein the surface of the resin sheet is embossed to have a center line average roughness Ra of from 0.05 to 2.0 .mu.m and a number of peaks Pc of from 5 to 500 peaks/8 mm.
