PURPOSE: To manufacture an induction electric heating coil simply and accurately which is used in an electromagnetic cooking unit and the like.

CONSTITUTION: A wire rod 1 having a desired diameter or a heat resistant insulating coating applied wire rod is wound roughly in a spiral shape by means of a coil winding machine 2, and after this is molded so as to keep spiral intervals constant and is fixed temporarily, this is pressurized, and is formed in a desired flat spiral shape. This is embedded directly or embedded in a molding jig 5, and a spiral shape is molded, and afterwards, this is fixed by means of heat resistant insulating adhesive 6.
