1. A capacitor comprising:
an electrode layer section comprising a plurality of layered inner electrodes facing each other and sandwiching dielectric layers, and via electrodes formed in a direction normal to the planes along which the inner electrodes are layered for passing current among the inner electrodes, and
a dielectric layer section comprising a plurality of dielectric layers provided over the electrode layer section at an upper surface side of the capacitor,
wherein the dielectric layer section includes inner electrodes facing each other and sandwiching dielectric layers, the space between the inner electrodes in the dielectric layer section being wider than the space between the inner electrodes in the electrode layer section, and
the via electrodes electrically connect the inner electrodes in the dielectric layer section.
