The present invention aims to provide a method for manufacturing a solar cell module capable of improving positioning accuracy of solar cell elements relative to a light reflection plate. When a solar cell module is manufactured, a corrugated light reflection plate 4 is first prepared by bonding a thermoplastic resin film 7 to a plastic substrate 6. Subsequently, the light reflection plate 4 is set on a lower mold 10, and a thick resin sheet 12 made from an encapsulation resin is arranged on the light reflection plate 4. Then, vacuum suctioning and hot-press processing are performed sequentially, whereby a precursor assembly 13 is formed with the light reflection plate 4 and the resin sheet 12 attached together. Subsequently, a plurality of solar cell elements 2 is placed on an upper surface of the precursor assembly 13. Then, a thin resin sheet 14 made from the encapsulation resin is arranged on the solar cell elements 2, and a front surface plate 3 is arranged on the resin sheet 14. Subsequently, a cross-linking reaction of the encapsulation resin proceeds with a dry laminator, thus the respective solar cell elements 2 are laminated.

Disclosed is a solar cell module capable of suppressing light leakage from a front plate and improving an optical confinement property. A solar cell module 1 includes a plurality of bifacial solar cell elements 2, a front plate 4 which is arranged on the front side of the solar cell elements 2, and a back plate 5 which is arranged on the back side of the solar cell elements 2 and has a light-reflecting surface 5a reflecting sunlight incident into the module from the module front side. When the refractive index of the front plate 4 is n, the inclination angle Φ (radian unit) of the light-reflecting surface 5a relative to the array direction of the solar cell elements 2 is set as follows between a cell interval center line A and a cell end line C. That is, in a region X between the cell interval center line A and a near-cell line D, the relationship (Φ>0.5×sin −1 (1/n) is established. In a region Y near the cell end line C, the relationship (Φ
