Patent ID: 7881040

Claim:
A feedthrough capacitor mounted structure in which a feedthrough capacitor is mounted on a mounting surface of a substrate, wherein the substrate is an insulating substrate internally having first and second conductor portions isolated from each other, and comprises a plurality of first via holes extending from the mounting surface to the first conductor portion, a plurality of second via holes extending from the mounting surface to the second conductor portion, a plurality of first land electrodes formed at respective positions corresponding to the first via holes on the mounting surface and connected to the corresponding first via holes, and a second land electrode formed on the mounting surface and connected to the second via holes in an isolated state from the first land electrodes, wherein the first via holes and the second via holes, when viewed from the mounting surface side, are arranged in a matrix pattern and alternately arranged in a row direction and in a column direction, wherein the feedthrough capacitor comprises an element body having a longitudinal direction, a pair of first terminal electrodes arranged on a pair of first end faces of the element body opposed in the longitudinal direction, and a second terminal electrode arranged on a second end face of the element body perpendicular to the longitudinal direction, wherein the feedthrough capacitor, when viewed from the mounting surface side, is located between a pair of said first via holes adjacent to each other in a direction intersecting with the row direction and also adjacent to each other in a direction intersecting with the column direction, wherein said pair of first terminal electrodes are connected to the respective first land electrodes corresponding to said pair of adjacent first via holes, and wherein the second terminal electrode is connected to the second land electrode.
