摘要： A melting furnace including a sealed container containing an inert gas atmosphere, a crucible that is located inside the sealed container and melts a raw material by induction heating, and a crucible cooling mechanism. The crucible cooling mechanism includes a pipe portion that includes an intake that communicates with the sealed container and enables the inert gas to be discharged from the sealed container, and an outlet that enables the inert gas to be introduced into the sealed container, a heat exchange portion that is located partway along the pipe portion, and a gas transporting portion that is located partway along the pipe portion.
