Abstract
Abstract This composite electronic part comprises a dielectric layer on which earth electrodes are formed, a dielectric layer on which conductive lines are formed, and a dielectric layer on which electronic parts are pattern-formed. A plurality of the dielectric layers are so laminated that the dielectric layer with the earth electrodes is disposed next to the dielectric layer with the conductive lines. These conductive lines and earth electrodes form strip lines. A short-stub or an open-stub is formed by connecting one end of the conductive line to the earth electrode or opening that one end. A composite electronic part is obtained by connecting the short-stub, open-stub, and the electronic parts.
