To provide a melting device, and a melting method preventing molten silicon leakage occurring before complete melting due to a structure and mechanism of the melting device, reducing scattering of molten silicon when tapping the molten silicon, miniaturizing the device, and capable of efficiently using silicon raw material.

In the melting device, silicon material inputted in a crucible 1 is heated and melted by a heating means 3, and it is tapped from a tap hole 5 provided in a crucible bottom. It is composed by providing a depression part 7 in the crucible bottom, and providing the tap hole in an interior of the depression part.
