Abstract
A ceramic capacitor comprises a ceramic sintered body, and first and second terminal electrodes formed on outer surfaces of the ceramic sintered body. The first terminal electrode is electrically connected to a land formed on a substrate through a first metal terminal. The first metal terminal has a first capacitor connecting portion mechanically connected to the first terminal electrode, a first terminal portion mechanically connected to the land, and a first intermediate portion electrically connecting the first capacitor connecting portion and the first terminal portion to each other. The first capacitor connecting portion of the first metal terminal is parallel to the substrate.

A ceramic capacitor mounting structure for mounting a ceramic capacitor to a substrate formed with first and second land electrodes;
- the ceramic capacitor comprising:
- a ceramic sintered body;
- first and second inner electrodes arranged so as to oppose each other with a ceramic interposed therebetween in the ceramic sintered body;
- a first terminal electrode electrically connected to the first inner electrode and formed on an outer surface of the ceramic sintered body;
- and
- a second terminal electrode electrically connected to the second inner electrode and formed on an outer surface of the ceramic sintered body;
- wherein the first terminal electrode is electrically connected to the first land electrode formed on the substrate through a first metal terminal;
- wherein the second terminal electrode is electrically connected to the second land electrode formed on the substrate;
