NOVELTY - The sheet (100) has warp and weft which are made to cross each other and twisted. The fiber density of weft (11) and warp (12) is 8-20 meshes. A silicon rubber layer (20) is covered by the outer surface of pressure resistant fabric layer (10). The silicon rubber layer has a lower surface (21) of lower surface side of fabric layer, and upper surface (22) of upper surface side of fabric layer. The upper surface and the lower surface of the silicon rubber layer are formed in an uneven shape, as the surface average roughness exists in the range of 0.005-0.7 micrometer.    USE - Silicone rubber sheet for thermo-compression bonding of printed circuit board used in solar cell.    ADVANTAGE - The sticking of the silicone rubber sheet to the mirror-finished surface is prevented so that workability is made favorable. The frequency of exchanging is prevented and the manufacturing cost is reduced while the silicone rubber sheet with excellent durability is obtained. Since the pressure resistance is improved, the heating-pressing operation is done favorably without any damage, and the productivity is improved.    DETAILED DESCRIPTION - The warp and weft are twisted in the range of 100-300. A primary edge portion of length direction and the secondary edge portion are provided. A side portion (130) of width direction is orthogonally crossed at the same plane as the side portion (140) of length direction. The width between edge portions is in the range of 600-4800 mm and the width between side portions is in the range of 500-4200 mm. The thickness between the upper surface and lower surface of the silicon rubber layer exists in the range of 0.75-20 mm.
