PURPOSE:To eliminate the need of providing a ground, to facilitate the handling by decreasing the number of parts, and to reduce the cost by decreasing the number of processes by constituting the magnetic head by fitting and installing directly an assembly of a core formed by installing a core in a bobbin with a coil and the bobbin with a core into a case and assembling them. CONSTITUTION:A core 3 is inserted through a base part bobbin 11 and a drum part bobbin 21 and contained, end parts of its front part are allowed to abut on each other through a gap spacer 8, and also, end parts of the rear part are allowed to abut on each other, and thereafter, an assembly 31 of the core 3, the base part bobbin 11 and the drum part bobbin 21 is inserted into a case, and engaged and assembled. In such a way, it is unnecessary to provide the ground, its handling can be facilitated by decreasing the number of parts, and also, by simplifying the centering of each part, the magnetic head which is small in size and whose cost is low can be obtained. |
