摘要:
A multi-layer ceramic electronic component includes a ceramic body and an external electrode, the ceramic body including a protective portion and a functional portion, the protective portion including an end surface facing in a first direction, circumferential surfaces connected to the end surface and extending in the first direction, and a ridge that includes a recess extending along the first direction and connects the circumferential surfaces, the functional portion being disposed inside the protective portion, the external electrode including a base film covering the end surface, an intermediate film formed on the base film, and a surface film formed on the intermediate film, the base film including a first covering portion formed on the end surface, second covering portions formed on the circumferential surfaces, and a third covering portion formed on the recess and spaced apart from at least one second covering portion, the intermediate film continuously covering the first, second, and third covering portions.
