PROBLEM TO BE SOLVED: To provide an enameled core wire induction heating device installed to an enameled wire production line which makes a vanish painting device quickly paint with few number of operation without generating bubbles so as not to damage the appearance when applying vanish to the core wire, and improve the production speed and production efficiency. SOLUTION: The enameled core wire induction heating device 30 is assembled in a vanish painting device applying vanish to the core wire 10 at a vanish pot 14 and repeating heating and drying operation at a heat drying furnace 18 several times. The heating device 30 is constructed by forming a notched part (a space) 31 through which, the core wire 10 is passed, to a ring-shaped iron core 32 for induction heating on which, several turns of induction heating coil 34 in which, alternating current is flowing, are wound. Induction current flows through the core wire 10 as a conduction body passing through the notched part 31 when the alternating current is made flow through the induction heating coil 34, and heats the vanish layer applied on the core wire 10 from its inside ( core wire 10 side).
