A magnetic head includes first to third coils, a main pole, a write shield, first and second yoke layers, and first and second coupling parts. The first and second yoke layers are magnetically connected to the write shield. The first yoke layer is located on the leading side relative to the main pole, whereas the second yoke layer is located on the trailing side relative to the main pole. The first coupling part magnetically couples the main pole and the second yoke layer to each other. The second coupling part magnetically couples the first yoke layer and the second yoke layer to each other. The first coil is wound around the first coupling part, whereas the second and third coils are wound around the second coupling part.
