Patent ID: 8072732

Claim:
A capacitor comprising: a plate-like capacitor main body having a thickness direction and including a capacitor main surface and a capacitor rear surface; and a plurality of capacitor via conductors provided in the capacitor main body and extending in the thickness direction of the capacitor main body, the plurality of capacitor via conductors including power supplying via conductors and grounding via conductors; wherein the capacitor main body is comprised of: a first dielectric laminated portion having a laminated structure including: a plurality of first dielectric layers; and a plurality of inner electrodes including power supplying inner electrodes and grounding inner electrodes which are alternately laminated by sandwiching the first dielectric layers, the power supplying inner electrodes connected only to the power supplying via conductors, the power supplying via conductors penetrating each of the power supplying inner electrodes so that the power supplying inner electrodes are electrically connected to each other, the grounding inner electrodes connected only to the grounding via conductors, the grounding via conductors penetrating each of the grounding inner electrodes so that the grounding inner electrodes are electrically connected to each other; and a second dielectric laminated portion having a laminated structure including: a plurality of second dielectric layers; a plurality of dummy electrodes unconnected to the peripheral portion of the plurality of capacitor via conductors, alternately laminated and disposed so as to be exposed at a surface portion of the capacitor main body; and a plurality of second, land-shaped conductors connected to the peripheral portion of each of the plurality of capacitor via conductors and formed in the plurality of second dielectric layers in common with an associated dummy electrode.
