Zusammenfassung:	To provide a leaching method of Sn and a manufacturing method of Sn, capable of suppressing reduction of leaching rate of Sn.SOLUTION: A leaching method of Sn includes a Sn leaching process for leaching Sn to Sn scum containing Pb by using a leaching liquid, and a solid-liquid separation process for conducting solid-liquid separation on the leaching liquid within 1.5 hr. after completion of leaching of Sn in the Sn leaching process.SELECTED DRAWING: Figure 1 【課題】Ｓｎの浸出率低下を抑制することができるＳｎの浸出方法およびＳｎの製造方法を提供する。【解決手段】Ｓｎの浸出方法は、Ｐｂを含むＳｎスカムに対し、浸出液を用いてＳｎを浸出するＳｎ浸出工程と、前記Ｓｎ浸出工程におけるＳｎの浸出の終了後、１．５時間以内に前記浸出液に対して固液分離を行う固液分離工程と、を含むことを特徴とする。【選択図】図１
