Provided is a solar cell module wherein a rear surface protective sheet has excellent long-term durability, and transmissivity of ultraviolet that reaches the solar cell is retained for a long time. This solar cell module is configured by laminating a front surface protective sheet, a light receiving-side sealing sheet, a solar cell element, a rear surface-side sealing sheet, and a rear surface protective sheet in this order. The solar cell module is characterized in that the light receiving-side sealing sheet has a transmissivity of 50 % or more with respect to light having a wavelength of 300 nm, and the rear surface-side sealing sheet contains a reactive ultraviolet absorbent.
