A combination type thin film magnetic head including an inductive type thin film writing magnetic head and a magnetoresistive type thin film reading magnetic head successively stacked on a substrate is manufactured in the following matter. A recessed portion is formed in a surface of the substrate 21, a first insulating layer 26, a first magnetic layer 27 and a thin film coil 29 isolated by a second insulating layer 28. A pole portion 32 is formed such that it is opposed to a pole portion of the first magnetic layer 27, and a second magnetic layer 34 is formed such that the third magnetic layer is brought into contact with the pole portion and is coupled with the first magnetic layer 27 at a position remote from an air bearing surface. Then, a MR reproducing element 40 embedded within a shield gap layer 35 is formed, and a third magnetic layer 37 is formed on the shield gap layer 35. By controlling a thickness of the first insulating layer, the throat height of the inductive type thin film magnetic head can be adjusted independently from the MR height of the magnetoresistive type thin film magnetic head. Therefore, the throat height, apex angle and MR height can be formed accurately, while the throat height can be controlled without destroying a good balanced condition between the throat height and the MR height.
