A lower shield layer and an upper shield layer are formed to have a planar shape, and a detecting element is provided between the lower shield layer and the upper shield layer. End faces of the upper shield layer may extend farther in a depthwise direction from a surface facing a recording medium than end faces of the lower shield layer. A lower conductive electrode may be disposed directly adjacent to a facing inner surface of the lower shield layer. An upper conductive electrode may be disposed adjacent to a portion of the upper shield layer. Therefore, the lower shield layer and the upper conductive electrode may be insulated from each other.
