To provide a solar cell with a back sheet, which includes a back sheet having excellent withstand voltage property and being capable of sufficiently suppressing delamination even under a high-temperature environment.

A solar cell with a back sheet 300 includes a solar cell 100 and a back sheet 200 for covering and protecting a rear surface 100b of the solar cell 100. The back sheet 200 includes a metal layer 30 and a resin layer 40 laminated on the side opposite to the solar cell 100 with respect to the metal layer 30. The metal layer 30 is constituted of a metal material containing aluminum. The resin layer 40 contains a polyolefin having a gel fraction of 40% or more.
