PROBLEM TO BE SOLVED: To make a resin heating temperature uniform by stabilizing a temperature distribution in a hot tip by regular winding of an induction heating winding coil wire. SOLUTION: An induction heating hot tip for a mold for injection molding comprises a bobbin 2 having a partition wall 2a on which an induction heating coil 1 is wound in a manner of regular winding, and a non-dielectric layer 4 used also as a heat insulation and disposed at an outside of the bobbin 2 to manage a winding position and the number of turns. Thus, after the coil 3 is energized, a heating quantity to be induction heated at a heating element 5 can be accurately managed, and the temperature and the heating position of the resin 6 to be heated can be arbitrarily set.
