  • Patent number: 11011309
    Abstract: Disclosed is a ceramic electronic component having external electrodes on each of opposed end portions of a rectangular parallelepiped component body. A first direction dimension, a second direction dimension and a third direction dimension of the component body satisfy a condition of second direction dimension>first direction dimension>third direction dimension. The external electrodes are of a five-face type having a first face portion, a second face portion, a third face portion, a fourth face portion and a fifth face portion. At least one edge of the fourth face portion and the fifth face portion of the external electrode has a recess portion recessed from the edge toward the first face portion. Both side portions in the third direction of the recess portion are covering portions which cover ridge portions of the two faces in the second direction of the component body.
