A thin film magnetic head comprising a substrate, a lower magnetic pole provided on the substrate, a write gap layer located on the lower magnetic pole, and an upper magnetic pole located on the gap layer, the upper magnetic pole including a plating base layer in contact with the gap layer, wherein the plating base layer of the upper magnetic pole is made of a magnetic film having a saturation magnetic flux density of 1.2 T or larger. The thin film magnetic head has an increased recording density, and is adapted to recording at an increased frequency.
