A multi-layer ceramic electronic component includes a ceramic body and an external electrode. The ceramic body includes a first side surface facing in a direction of a first axis, a second side surface facing in a direction of a second axis orthogonal to the first axis, a ridge that connects the first side surface and the second side surface to each other, and internal electrodes laminated along a third axis orthogonal to the first axis and the second axis and led out in a lead-out region. The external electrode includes a protrusion provided at a position along the ridge and protruding in the directions of the first axis and the second axis, and a first base portion and a second base portion extending from the protrusion along the first side surface and the second side surface, respectively, the external electrode covering the lead-out region.
