Claims

[Scope of utility model registration request]

A first core with a U-shaped cross section and a first winding in the center, and a second winding in the center with a cross section of the same shape as the first core and narrower than the first core. a second core that is butted against each other so as to form a loop-shaped magnetic path with the first core; and on both sides of the abutment surface of the first core and the second core two third cores are butted against each other to form a loop-shaped magnetic path with the second core, and the exposed surface of the magnetic gap formed by the second core is substantially rectangular; A magnetic gap material disposed between the first and second cores and extending therefrom between the first core and the third core at one of the abutting portions of both ends of the core and the second core. and, thereby, the above-mentioned first
A magnetic gap having the width of the first core is provided for the magnetic flux passing through the core, and a part of the magnetic gap provides a magnetic gap for the magnetic flux passing through the second core. magnetic head.
