Claim:
1. A solar cell module manufacturing method comprising: preparing a front-side transparent protective member and a back-side protective sheet member, the front-side transparent protective member comprising a first principal surface and a second principal surface, a surface area of the first principal surface being larger than a projected area of the first principal surface, a surface area of the second principal surface being larger than a projected area of the second principal surface, the back-side protective sheet member comprising a third principal surface and a fourth principal surface, a surface area of the third principal surface being larger than a projected area of the third principal surface, a surface area of the fourth principal surface being larger than a projected area of the fourth principal surface; and disposing solar cells between the second principal surface of the front-side transparent protective member and the third principal surface of the back-side protective sheet member, and sealing the solar cells with a bonding layer therebetween such that the solar cells comprise a first solar cell and a second solar cell, a negative value being calculated by multiplying a slope of a tangent line to a main surface of the first solar cell by a slope of a tangent line to a main surface of the second solar cell with respect to a horizontal plane in a cross sectional view of the solar cell module, wherein a thermal contraction rate of the back-side protective sheet member is 1% or more.
