ABSTRACT:
A capacitor parts of the present invention, includes a substrate, a plurality of capacitor elements arranged on the substrate and composed of a lower electrode, a dielectric layer, and an upper electrode respectively, a lower electrode rewiring layer formed over the plurality of capacitor elements and connected electrically to lower electrodes of the plurality of capacitor elements respectively to act as a common electrode, and an upper electrode rewiring layer formed over the plurality of capacitor elements and connected electrically to upper electrodes of the plurality of capacitor elements respectively to act as another common electrode, wherein the plurality of capacitor elements are connected electrically in parallel in a state of the capacitor parts, thus, the impedance is reduced in a wide high-frequency band by changing impedances among the plurality of capacitor elements.
