To provide a recycling method for a solar cell module capable of high-quality and high-yield selection of each resin material from a resin concentrate obtained by pulverization of a solar battery cell-bearing back sheet separated from a solar cell module, followed by screening.SOLUTION: A recycling method for a solar cell module includes a selection step of screening a pulverization product obtained by pulverization of a solar cell module, followed by sinkable separation of an obtained resin concentrate with a liquid for heavy liquid selection to a low-specific gravity resin and a high-specific gravity resin.SELECTED DRAWING: None 【課題】太陽電池モジュールから分離した太陽電池セル付きバックシートを粉砕した後、篩分して得られた樹脂濃縮物から樹脂素材毎に高品位かつ高収率に選別することができる太陽電池モジュールのリサイクル方法の提供。【解決手段】太陽電池モジュールを粉砕した粉砕物を篩分して得られた樹脂濃縮物を液体で浮沈分離することにより低比重樹脂と高比重樹脂とに重液選別する選別工程を含む太陽電池モジュールのリサイクル方法である。【選択図】なし
