ABSTRACT:
A lower shield layer has a substantially flat shape, and an upper shield layer has a front portion and a rear portion, where the front portion is disposed closer to the lower shield layer than the rear portion. A lower conductive electrode and an upper conductive electrode are disposed between the lower shield layer and the upper shield layer. The lower conductive electrode is electrically connected to the lower shield layer, and the upper conductive electrode is electrically connected to the upper shield layer. Since the lower and upper conductive electrodes are disposed between the upper and lower shield layers, each of the lower shield layer and the upper shield layer may be formed to have a small area and a simple shape.
