<p><P>PROBLEM TO BE SOLVED: To provide a back-united sheet capable of preventing a sealing material, fluidized and protruded from a peripheral edge, from sticking on a release sheet during vacuum heating lamination using the release sheet. <P>SOLUTION: The back-united sheet 1 has the sealing material 3 and a back sheet 2 united in a laminated state, wherein only the back sheet 2 is present at the peripheral edge thereof, and the sealing material 3 is not present. A belt-like unlaminated portion 25 is formed, preferably, to a width of 2 to 15 mm. Consequently, the sealing material 3 fluidized and protruded from nearby the peripheral edge of the back-united sheet 1 stays on the unlaminated portion 25 of the back-united sheet 1, and a peripheral edge surface of the solar cell module except the unlaminated portioni 25 during the vacuum heating lamination, thereby preventing the sealing material from sticking on the back-side release sheet and/or a top-side release sheet. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
