Abstract

See full text

An LC composite component employing a ceramic sintered body obtained by laminating pluralities of magnetic green sheets and dielectric green sheets and cofiring the same. The ceramic sintered body is provided therein with a magnetic region and a dielectric region along the direction of thickness. The magnetic region of the sintered body is provided with at least one inner electrode layer which extends to first opposite side surfaces of the sintered body, thereby to define an inductance unit. The dielectric region is provided with a plurality of electrodes oppositely arranged through the dielectric substance, which plurality of electrodes includes first and second electrodes. A pair of first outer electrodes are formed on the first side surfaces of the sintered body, to be electrically connected with the inner electrode formed in the magnetic region. The first electrode in the dielectric region is electrically connected with at least one of the first outer electrodes, and the second electrodes is connected with a second outer electrode which is formed on another surface of the sintered body.
