MANUFACTURING METHOD OF FILLING MATERIAL SHEET FOR SOLAR BATTERY MODULE AND MANUFACTURING METHOD OF SOLAR BATTERY MODULE

PROBLEM TO BE SOLVED: To provide a manufacturing method capable of producing with high efficiency a filling material sheet for a solar battery module on the surface of which an unevenness shape little in irregularities is formed. SOLUTION: The manufacturing method has the step of forming a resin sheet by melting and extrusion-molding a composition for forming the filling material that contains a thermoplastic resin and the embossing step of forming the unevenness on the surface of the resin sheet by using a shaping roller 2 having an unevenness shape on its surface and a pressing roller 3 having a surface temperature lower than that of the shaping roller 2 and pressing the resin sheet fabricated by the above melting and extrusion molding step against the surface of the shaping roller 2 with the pressing roller 3. The temperature difference (Te-Tp) between the surface temperature (Te) of the shaping roller 2 and that (Tp) of the pressing roller is set within a range of 2-40°C. COPYRIGHT: (C)2007,JPO&INPIT
