A multi-layer ceramic electronic component includes: a ceramic body including first and second main surfaces facing in a first axis direction, first and second end surfaces facing in a second axis direction, and first and second internal electrodes; a first external electrode including a first cover portion covering the first end surface, and a first extended portion extending from the first cover portion to the second main surface; and a second external electrode including a second cover portion covering the second end surface, and a second extended portion extending from the second cover portion to the second main surface, the multi-layer ceramic electronic component satisfying that, when Trepresents a dimension of the ceramic body in the first axis direction and Trepresents a dimension of each extended portion in the first axis direction, T+Tis 50 &#x3bc;m or less, and T/(T+T) is 0.32 or less.

Multi-layer ceramic electronic component

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&#x3e;first direction dimension&#x3e;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.
