/Multilayer Ceramic Capacitor
Abstract

A ceramic capacitor includes a body including dielectrics and internal electrodes layered in layering direction, the body including first and second main surfaces opposed in the layering direction, first and second side surfaces opposed in width direction orthogonal to the layering direction, and first and second end surfaces opposed in length direction orthogonal to the layering and width directions, and an external electrode on the first and second end surfaces and electrically connected to the internal electrodes, wherein each of the internal electrodes includes a narrow portion and a drawn portion on opposite sides of a central portion, the drawn portion connecting the central portion to the external electrode, the narrow portion being narrower in the width direction than the central portion, and a coating including Si and K at an end in the width direction and at the central portion in the length direction of the internal electrodes.
