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.
