ABSTRACT:
A composite electronic part includes a dielectric ceramic portion consisting of a Pb group dielectric material. Inside the dielectric ceramic portion, an internal electrode constituting a portion of a capacitor is formed. The dielectric ceramic portion is bonded to a magnetic ceramic portion consisting of a Ni--Zn group ferrite material by an intermediate layer consisting of a ceramic material containing Pb, Ni, Fe and Nb as main components. Inside the magnetic ceramic portion, an internal electrode constituting a portion of an inductor is formed. Furthermore, at end portions of the dielectric ceramic portion, intermediate layer and magnetic ceramic portion, a plurality of external electrodes consisting of, for example, Ag are formed, and connected to the predetermined internal electrodes.
