Ceramic capacitor mounting structure and ceramic capacitor

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.
