The first layer has an end face located in a medium facing surface. An end face of each of the second and third layers closer to the medium facing surface is located at a distance from the medium facing surface. A first nonmagnetic layer is disposed around the first layer. A second nonmagnetic layer is disposed between the medium facing surface and the end face of the second layer closer to the medium facing surface.
