摘要:
A multi-layer ceramic electronic component includes (I) a ceramic body including (i) a protective portion that includes an end surface facing in a first direction, circumferential surfaces, and a ridge including a recess extending along the first direction and connects the circumferential surfaces, and (ii) a functional portion including internal electrodes laminated in a second direction, and (II) an external electrode including (i) a base film covering the end surface and including a first, second, and third covering portions formed on the end surface, on the circumferential surfaces, and on the recess, respectively, (ii) an intermediate film formed on the base film and continuously covering the first, second, and third covering portions, and (iii) a surface film formed on the intermediate film, wherein the recess is disposed outside end portions of the internal electrodes in a third direction orthogonal to the first and second directions.
