(2) The applicator according to claim 1, wherein the induction heating applicator has a simple structure in which the magnetic path excluding the magnetic pole air portion of the magnetic core has an open magnetic path structure. (3) As the induction type applicator, the magnetic core part is configured in a T-shape, and a coil is wound around each core part so that the lines of magnetic force are concentrated at the magnetic pole part, and the generated magnetic field is reduced by creating an open magnetic path structure. The applicator according to Claim 1 of the Utility Model Registration Claim, which has a reinforced structure. (4) The induction heating applicator has a structure in which a flat conductor is wound around the magnetic core instead of a normal coil around the magnetic pole core, and the structure can be used even at high frequencies in the RF band, as described in claim 1. applicator. (5) The applicator according to claim 1, which is a utility model, and has a structure in which a magnetic lens in the form of a donut-shaped conductor disk is housed in a cooling bolus and can be cooled with a dielectric liquid such as silicone oil. (6) The applicator according to claim 1, which has been registered as a utility model and is provided with a magnetic lens having a cooling effect by circulating diamagnetic solvent in a donut-shaped bolus made of silicone rubber or the like. (7) An application having a structure characterized in that a groove is provided in the magnetic core of the open magnetic circuit structure according to claim 2, and a coil is wound so as to be embedded in the groove to reduce line capacitance. Ta. (8) A coil is wound in a space away from the surface of the magnetic core of the open magnetic circuit structure according to claim 2, and the impedance looking into the coil is reduced using a superconducting coil or an amorphous coil to drive the coil. applicator.
