Abstract

PURPOSE:To reduce the leakage magnetic flux of an electromagnetic device and to reduce the noise of the device by mounting a coil unit at a main magnetic path iron core and bonding the magnetic material of the width longer than the distance between both ends of a main magnetic path iron core at least to the main magnetic path iron core. CONSTITUTION:A leakage path 9 is projected at the central side surface from the laminated iron core at a substantially H-shaped main magnetic path iron core 10. Coil bobbins 5 are provided at both side peripheries of the path 9, and the primary and secondary coils 3, 4 are wound on these bobbins 5. The magnetic material sheet 11 has a width wider than the entire length of the iron core 10, suitable number of laminates are wound directly on the outer periphery of the iron core 10 including the coil unit made of the primary and secondary coils 3, 4 and the bobbins 5 to operate as the external magnetic path and the case.
