PROBLEM TO BE SOLVED: To provide a coil-heating device where a coil part is effectively heated with a simple structure without thermal deformation of a core, while adopting a high-frequency induction heating means. SOLUTION: In the coil-heating device, a coil part L wound to the core F is heated by high-frequency magnetic flux generated in a head coil 3 of the high-frequency induction heating means 1. The head coil 3 is constituted of at least a pair of loop-like parts 3A and 3B, whose generation directions of high-frequency magnetic fluxes HA and HB become mutually opposite.
