Claims

[Scope of utility model registration request]

a first core having a cross-sectional shape of 3 and having a first winding in the central part; 2C winding is applied to the above first
a second core located at one end of the abutting surface of the cores and abutted against each other so as to form a loop-shaped magnetic path with the first core, and a breaking point having the same shape as the first core; The second core C, which has a U-shaped opening direction in the same direction as the second core and has a concave portion on its side face that receives the second isoline, is closely juxtaposed with a magnetic gap material on both sides, and A third core abutted against the first core in the same way as the second core, and at one of the abutting portions of both ends of the first core and the second core, the first and second cores are abutted against the first core. a magnetic gap material extending between the cores and between the first core and the third core; 1. A magnetic head according to claim 1, characterized in that a magnetic gap having a core width of 1 is provided, and a portion of the magnetic gap provides a magnetic gap of 1 to the magnetic flux passing through the second core.
