Abstract
A magnetic head includes a coil, a main pole, a write shield, a first insulating film, and a second insulating film. The coil includes a specific coil element. The main pole has a top surface including an inclined surface portion and a flat surface portion. The write shield includes an inclined portion. The inclined portion includes a first portion opposed to the inclined surface portion, and a second portion located farther from a medium facing surface than the first portion. The specific coil element includes an interposition part interposed between the flat surface portion and the second portion. The first insulating film is interposed between the inclined surface portion and the first portion of the inclined portion, and between the interposition part and the second portion of the inclined portion. The second insulating film is interposed between the first insulating film and the second portion of the inclined portion.
