Abstract
A thin-film magnetic head includes a coil, a magnetic path forming section, and an insulating film. The magnetic path forming section includes first and second magnetic material portions. The coil includes first and second coil elements located between the first and second magnetic material portions. The insulating film includes an underlying portion located under the first and second coil elements. In a method of manufacturing the thin-film magnetic head, the insulating film is formed to cover the first and second magnetic material portions, and then a seed layer is formed selectively on the underlying portion of the insulating film. The coil is formed by plating using the seed layer.
