Thin film magnetic head and method of manufacturing thin film magnetic head

A thin film magnetic head comprising:

• two magnetic layers magnetically coupled to each other and having two magnetic poles which face each other with a gap layer in between and face a recording medium;
• a thin film coil extending between the two magnetic layers in the direction where the two magnetic layers extend, and having a spiral winding structure around a coupling position of the two magnetic layers;
• and
• an insulating layer for insulating the thin film coil from the two magnetic layers,
• wherein a first hierarchical pattern which is a part of the thin film coil, a separate layer made of an insulating material and a second hierarchical pattern which is coupled to the first hierarchical pattern and is another part of the thin film coil are laminated in this order, and
• the first hierarchical pattern, the separate layer and the second hierarchical pattern are disposed in the same position so as to fully overlap one another, and have the same planar shape.
