PROBLEM TO BE SOLVED: To provide an apparatus for electromagnetic induction heating which facilitates the working of a magnetic metal plate and blocks distortions in the cast molding while completely preventing such a failure as slipping off the body of the apparatus. SOLUTION: The apparatus is provided with an apparatus body 1 made of a non-magnetic metal material, a magnetic plate 4 provided on the rear of a bottom part 2 and a plurality of raised cut pieces 5 provided in the magnetic metal plate 4. The raised cut pieces 5 are so formed as to make their bending sides radial from the center of the bottom part 2 while protruding outward from the bottom part 2 so that the erected cut pieces are filled with the non-magnetic metal material of the body 1 of the apparatus to be integrated with the body 1 of the apparatus. This reduces the resistance which is caused by the raised cut pieces 5 against the non-magnetic metal material when it flows, thereby achieving a molding without distorting the magnetic metal plate 4 while securing a joint force with the body 1 of the apparatus.
