A magnetic head includes a coil, a main pole, a write shield, a gap part, and a return path section. The return path section is located on the front side in the direction of travel of a recording medium relative to the main pole, and connects the write shield and part of the main pole away from a medium facing surface to each other. The coil includes a specific coil element. The main pole has a top surface including an inclined portion and a flat portion. The write shield has an inclined surface. The inclined surface includes a first portion opposed to the inclined portion with the gap part therebetween, and a second portion located farther from the medium facing surface than the first portion.
