MULTILAYER CERAMIC ELECTRONIC COMPONENT

摘要

A multilayer ceramic electronic component includes a ceramic body having an end surface and a side surface adjacent to thereto such that the end surface and the side surface meet at an edge. The ceramic body has a plurality of internal electrodes with adjacent pairs of the internal electrodes being separated by a respective ceramic layer. An external electrode containing a metal, an inorganic component and voids is electrically connected to at least some of the internal electrodes and both covers the end surface and extends over the edge onto the side surface to form an extending-around portion which extends at least 50 μm onto the side surface as measured in a direction perpendicular to the edge and ends at a leading edge remote from the edge. A portion of the extending-around area which extends 50 μm from the leading edge towards the edge has an average occupancy area ratio which is at least 25 but not greater than 75. The occupancy area ratio is the ratio between the area of the conductive component and an area of the inorganic component on the one hand to the area of the conductive component, the area of the inorganic component and the area of the voids on the other.
