Abstract
Abstract A composite component includes a main body which is constituted by combining a first block which is made of dielectric material and contains capacitor electrodes, with a second block which is made of magnetic material and contains inductor electrodes. The main body is provided with recesses for receiving other components and connection electrodes to which the other components are connected. The connection electrodes are themselves connected to lead-out electrodes. The main body is further provided with external electrodes for connection to the capacitor electrodes, the inductor electrodes and the lead-out electrodes.
