A chip-like electric component such as a chip resistor is provided, which is easy to manufacture and in which cracks or fractures of an insulating substrate are unlikely to occur. The center electrode assembly includes an electrode assembly wherein a plurality of center electrodes extend outward from the center planar portion thereof at a predetermined angular distance; and a ferrite. Because of the differential operation of the CPP GMR sensor of this invention, there is no need for shield layers to screen the sensor from stray magnetic fields.
