PROBLEM TO BE SOLVED: To provide a sealant roll for a solar cell capable of feeding out a sealant sheet having excellent transparency and dimensional stability.SOLUTION: A sealant roll 10 for a solar cell is obtained by rolling up a sealant sheet 11, and the sealant sheet 11 is formed from a resin composition containing a polyethylene-based resin. The sealant roll 10 for the solar cell satisfies following conditions (a), (b) of (a) a tension T1 in the case where the sealant sheet 11 within 5 m from the end of winding around a winding core 12 is fed out of the sealant roll 10 for the solar cell at a speed of 5 m/min and a tension T2 in the case where the sealant sheet 11 within 5 m from start of winding around the winding core 12 is fed out of the sealant roll 10 for the solar cell at a speed of 5 m/min are a width of 100 N/1000 mm or less and (b) a storage elastic modulus E1 of the sealant sheet 11 within 5 m from the end of winding around the winding core 12 at 20°C and a storage elastic modulus E2 of the sealant sheet 11 within 5 m from the start of winding around the winding core 12 at 20°C are 1 MPa or more and 50 MPa or less. |
