PURPOSE:To prevent the degradation of electromagnetic conversion characteristic and to extend the track width by coupling a magnetic body to a block, where a high saturation magnetic flux density film is stuck to a part of the slope of a first groove, with a magnetic gap material between them to form a core block. CONSTITUTION:A first groove 12 having a slope S2 is formed on the end face of a high permeability magnetic material block 1, and a second groove 4 deeper than the first groove 12 is formed in the position connected to the first groove 12 in parallel with this groove 12, and a high saturation magnetic flux density film 2 is stuck to a part of the slope S2 of the first groove 12. Magnetic bodies 1 and 1 are coupled to the block, to which the high saturation magnetic flux density film 2 is stuck, with a magnetic gap material 3 between them, and this core block is cut in the direction perpendicular to the first groove 12. Thus, a magnetic head is inexpensively obtained which has not a bad influence upon the electromagnetic conversion characteristic by the contour effect and facilitates extension of the track width.
