PROBLEM TO BE SOLVED: To provide a thin-film solar battery module capable of improving workability to a glass surface.SOLUTION: In a thin-film solar battery module that sequentially has a surface protection layer, a first encapsulation layer, a thin-film solar battery element, a second encapsulation layer, and a rear face transparent protection layer, a longitudinal elastic modulus at 25°C (a squeezing temperature) of the encapsulation layer is equal to or more than 1×10Pa, and a sum of thicknesses of the first encapsulation layer and the second encapsulation layer is 10 μm or more and 110 μm or less.SELECTED DRAWING: Figure 1 |
