The magnetic pole is provided between the first and second shields. The trailing shield is separated from the magnetic pole. The first shield includes first magnetic layers and first nonmagnetic layers arranged alternately along a first stacking direction. The first nonmagnetic layers include at least one selected from the group consisting of Ru, Cu, and Cr. Thicknesses of the first nonmagnetic layers each is not less than 0.3 nanometers and not more than 2.2 nanometers.
