To provide an induction melting furnace for use in dissolving metals and obtaining alloys of desired components and being capable of preventing molten metals from spreading over a bottom surface, when the metal is tapped from a tapping part provided at the bottom.

A gas spray 18 for spraying an inert gas 20 to a molten metal 13B, located at least on the lower edge of a communication hole 2a, is provided near the bottom surface 2b of the tapping part 2. The bottom surface of the tapping part is tapered, from the outer periphery of the bottom surface to the lower edge of the communication hole 2a.
