PURPOSE:To easily execute a work such as handling and a position adjustment, etc., to prevent a magnetic core from being damaged and to improve the yield by constituting the titled head so that a fitting part to the magnetic core of a core holder can be opened and closed freely, the magnetic core can be fitted in a state that the fitting part has been opened, and the fitting part is closed after the fitting. CONSTITUTION:A core holder 6 is divided into two roughly equal parts in the width direction of a front core and a back core. By using plastic, etc. having a suitable elasticity, as the material of the core holder 6, holder half bodies 60, 61 are constituted so as to be freely openable and closeable as indicated with an arrow B by using an A-A' line running along a hinge part 6d as an axis. The front core and the back core are fitted to the core holder 6 in a state that a fitting part 6a has been opened, therefore, a work such as handling of both the cores in case of fitting, a position adjustment of both the cores, and press fitting of a plate spring, etc. can be easily executed. In this way, the man-hour is decreased, and the time required for the assembly can be shortened. Also, a damage such as a chip, a crack, etc. caused by a handling failure of both the cores is prevented and the yield of the head is improved.
