摘要:
A shield incorporates: a first layer, a second layer, a third layer, a first coupling portion, and a second coupling portion. The first layer has: a first surface located in a region of a medium facing surface forward of an end face of a pole layer along the direction of travel of a recording medium; a second surface opposed to the pole layer; and a third surface opposite to the second surface. The second layer touches the third surface. The third layer is disposed in a region sandwiching the pole layer with the first layer. The first coupling portion couples the first layer to the third layer without touching the pole layer. The second coupling portion is located farther from the medium facing surface than the first coupling portion and couples the pole layer to the third layer.
