PURPOSE:To discriminate the type of a magnetic head containing a bobbin having a winding even after a core assembly unit is set into a case and resin is filled, by providing a projected part at a part of the bobbin in such a way that the projected part is exposed to a part of the outer circumference of the magnetic head. CONSTITUTION:A thick part 3'b extended from the edge of a flange part 3'a of a bobbin 3' is formed as prolonged so that it is not buried by the filled resin even after set into a case 1 in the form of a core assembly unit 8. A colored material is used for forming the bobboin 3' for identification, and a winding is applied in response to the bobbin color. Otherwise a color corresponding to the difference of number of turns of the winding is added to the exposed part at the end of the part 3'b and immediately before or after the winding. In such a way, the type of a magnetic head can be identified even after the unit 8 is set into the case 1 and resin is filled therein. |
