Inductor built-in electronic parts using via holes
 A small inductor built-in electronic part whose Q is high is provided. An LC resonator comprises a laminate composed of a number of laminated electronic layers. Capacitor electrodes, common electrodes, and ground electrodes are formed between the dielectric layers. Two via holes are formed penetrating through the plurality of intermediate dielectric layers in the thickness direction thereof leaving a space therebetween. These via holes act as inductor elements.
