PROBLEM TO BE SOLVED: To provide a highly reliable magnetic head capable of preventing occurrence of pole erasing caused by residual magnetization of a laminated structure magnetic film even in the main magnetic pole of a narrow core width made to correspond to high recording density, and preventing output deterioration and data erasure. SOLUTION: A main magnetic pole 21 for generating a magnetic field for recording in a direction vertical to a medium opposite surface is provided with a laminated structure magnetic film 30 constituted of a plurality of magnetic layers 31 to 34 which are stacked in the thickness direction of the main magnetic pole 21 and where nonmagnetic layers 36 to 38 are interposed, and an end surface magnetic layer 35 which is formed along the stacked end surface of the medium opposite surface side of the laminated structure magnetic film 30 and where a surface opposite the stacked end surface becomes a medium opposite surface.
