PROBLEM TO BE SOLVED : To provide a method and device for recovering rare metals, capable of efficiently recovering the rare metals by use of manganese-oxidizing bacteria. SOLUTION : The method for recovering rare metals includes : supplying a substrate while falling a liquid containing manganese and rare metals over a microorganism holding member 21 which holds manganese-oxidizing bacteria and substrate-oxidizing bacteria. The manganese-oxidizing bacteria are bred by an organic substance generated by oxidizing the substrate by the substrate-oxidizing bacteria. The manganese is oxidized by the manganese-oxidizing bacteria to generate manganese oxide, rare metals are adsorbed by the manganese oxide, and the fallen manganese oxide is recovered.
