PROBLEM TO BE SOLVED: To provide an induction heating device which unnecessitates a funnel even in the case of being a small pouring hole in a mold. SOLUTION: The device is constituted with a crucible, in which plural electric conductive segments 2 are lined up as cylindrical state in the peripheral direction through an insulating body and also, a molten metal tapping hole 8 penetrated downward, is formed at the lower part, a coil wound on the outer periphery of this crucible and an electric source for supplying the current into this coil, and a surrounding project 11 which surrounds the molten metal tapping hole 8 and also, projects downward, is arranged at the segments 2.
