Ceramic capacitor and wiring board |
摘要 |
A ceramic capacitor includes a capacitor body and a metal layer arranged on an outer surface of the capacitor body. The outer surface includes: a first capacitor major surface; a second capacitor major surface opposite to the first capacitor major surface in a thickness direction of the capacitor body; and a capacitor lateral surface between the first and second capacitor major surfaces. The capacitor body includes a first layer section and a second layer section. The first layer section includes a plurality of ceramic dielectric layers and a plurality of internal electrodes, wherein the ceramic dielectric layers and the internal electrodes are layered alternately. The second layer section is exposed at the first capacitor major surface, and includes a corner portion at a boundary between the first capacitor major surface and the capacitor lateral surface. The metal layer covers the corner portion of the second layer section.
