ツド。[Claims for Utility Model Registration] A pair of cores made of ferromagnetic material are bonded by coating a metal magnetic film having a high saturation magnetic flux density on the bonding surface of at least one of the cores and on the inclined surfaces extending on both sides of the bonding surface. In the case where a magnetic gap is formed between the bonding surfaces of both cores with different track widths on the leading side and the trailing side with respect to the magnetic recording medium, at least one of the cores on the trailing side A magnetic head characterized in that the inclined surfaces on both sides of the bonding surface are bent at positions near both sides of the bonding surface, and the metal magnetic film on the inclined surface is locally thickened at the bent portions.
