PROBLEM TO BE SOLVED: To improve workability mounting a core in a cover without increasing a number of part items. SOLUTION: An electromagnetic shield core is formed by dispersing soft magnetic powder in resin or rubber, to be arranged in a lower surface of a magnetic flux generating coil. 14 of an electromagnetic induction heater. A core main unit 21 arranging the magnetic shield core 17 in a lower surface of the coil 14 and a mounting part 22 for mounting in a lower surface of the coil 14 are provided, the mounting part 22 is integrally formed in the core main unit 21. The mounting part 22 is preferably constituted by protruded parts 22a, 22b formed in a peripheral edge of the core main unit 21 and a mounting hole 22c or notch formed in the protruded part. A recessed part or recessed groove having a locking rib in both sides is formed in a resin-made cover, the core has an engaging part engageable with the locking rib in both sides, by engaging the engaging part with the locking rib, the core can be mounted also in the resin-made cover. |
