Title:
MULTILAYER CERAMIC ELECTRONIC COMPONENT, METHOD FOR PRODUCING SAME AND CIRCUIT BOARD
Document Type and Number:
WIPO Patent Application WO/2023/248562
Kind Code:
A1
Abstract:
A multilayer ceramic electronic component according to the present invention is provided with a ceramic element and an external electrode. The ceramic element has: a plurality of internal electrodes which are stacked in a first axis direction; and an end face from which the plurality of internal electrodes are led out, and which is perpendicular to a second axis that is orthogonal to the first axis. The external electrode comprises a base layer that is connected to the plurality of internal electrodes, while covering the end face. The plurality of internal electrodes and the base layer are configured from a polycrystalline body that is mainly composed of Cu. The average crystal grain size of the base layer is not less than 1.2 times those of the plurality of internal electrodes.
