PROBLEM TO BE SOLVED: To enhance line recording density by suppressing distortion of the bit pattern shape in a recording medium. SOLUTION: This thin film magnetic head is provided with a first and a second magnetic layers 8 and 14, a gap layer 9 provided between the first and the second magnetic layers 8 and 14 and thin film coil 10, the part of which is provided between the first, and the second magnetic layers 8 and 14. The second magnetic layer 14 has a magnetic pole part layer 14A and a yoke part layer 14B. The thin film magnetic head is further provided with a non-magnetic layer 15 coming into contact with the surface on the side opposite to the gap layer 9 of the magnetic pole part layer 14A. A part adjoining the surface on the side opposite to the gap layer 9 of the magnetic pole part layer 14A via the non-magnetic layer 15 among the york part layers 14B includes a layer 14B<SB>3</SB>coming into contact with the non-magnetic layer 15 and a layer 14B<SB>2</SB>coming into contact with at least a part of the surface on the side opposite to the non-magnetic layer 15 of the layer 14B<SB>3</SB>.
