A method for fabricating a thin film magnetic head is disclosed. A nonmagnetic gap layer is formed on a lower gap layer. A first insulating layer is formed on a first part of the nonmagnetic gap layer. A second part of the nonmagnetic gap layer not covered with the first insulating layer is a magnetic gap formation section, which is part of a tip region. A coil layer and a second insulating layer are formed on the first insulating layer. A first underlying layer composed of a magnetic material extending from the nonmagnetic gap layer inside the tip region is formed over the second insulating layer. A first magnetic material layer is formed on the first underlying layer outside the tip region. The first underlying layer is removed from inside the tip region. A nonmagnetic material layer extending from the nonmagnetic gap layer is formed over the first magnetic layer.
