PURPOSE:To improve regidity without applying compressive stress on a wound iron core, and to stabilize the quality of the title induction apparatus by obtaining excellent magnetic characteristics by a method wherein a side anchor member is provided at the upper corner part of the wound iron core, and both of them are integrally fixed. CONSTITUTION:A side anchor member 14 has an L-shaped cross section, a circular arc surface coinciding with the curvature of the corner part of an iron core 11 is provided as the inner part of the side anchor member 14, a recessed part is provided on the opposite surface. Also, a groove 15 is formed in the center part in width direction of the outside part, the circular arc surface is contacted to the outer circumferential surface of the corner part on the upper part of the core 11, the clamping band 12 on the outer circumferential surface of the core 11 is provided in the groove 15, each circular arc surface is contacted to the outer circumferential surface of the corner part on the upper part of the core 11, the clamping band 12 of the outer circumferential surface of the core 11 is provided in the groove 15, and each side anchor member 14 and the core 11 are integrally fixed. The aperture part 18a of an upper clamp 18 is inserted into the stepwide recessed part of the side anchor member 14, the core 11 and the winding 13 are supported, the lower part of the core 11 is housed and supported in the recessed part 19a of the lower clamp 19.
