PROBLEM TO BE SOLVED: To provide a manufacturing method of a thin-film magnetic head, by which GD andθbecome independently controllable. SOLUTION: This method includes: a process to form a high permeability layer 30 of a material having the permeability higher than that of a lower magnetic pole 23a, on a surface of the lower magnetic pole 23a to be confronted with an upper magnetic pole 26 through a gap layer 31 of the writing tip part side; a process to form the gap layer 31 on the high permeability layer 30; a process to form a 2nd insulation layer 35 on a 1st insulation layer 29 so as to reduce the level difference between the high permeability layer 30 and the 1st insulation layer 29, which is generated by the formation of the high permeability layer 30; and a process to form a 3rd insulation layer 36 having a drawing pen shaped part 33 while covering the 2nd insulation layer 35 and covering the required parts of the lower magnetic pole 23a.
