A multi-layer ceramic electronic component includes a ceramic body and an external electrode. The ceramic body includes an end surface facing in a first direction, and internal electrodes exposed from the end surface and laminated in a second direction orthogonal to the first direction. The external electrode is provided on the end surface and includes two protrusions that are formed along two peripheral portions of the end surface and protrude in the first direction, the two peripheral portions being disposed in a third direction orthogonal to the first direction and the second direction.
