A sealing material sheet is provided which can reduce an amount of air infiltrated into a laminate in the step of laminating constituent members of a solar cell module and can shorten the time necessary for the heating and degassing process in a vacuum in the solar cell module manufacturing process. The sealing material sheet is used as a member of a solar cell module formed by heating and pressing a laminate in which a first protective member 5, a first sealing material sheet 6, a photoelectric conversion cell 7, a second sealing material sheet 8, and a second protective member 9 are laminated in this order, an uneven pattern is formed on one surface or both surfaces of the first sealing material sheet 6 and the second sealing material sheet 8 through an embossing process, and the embossing process is performed so that the porosity of the first sealing material sheet 6 and the second sealing material sheet 8 is in the range of 1% to 4%. |
