摘要： A multi-layer ceramic electronic component includes a ceramic body and an external electrode. The ceramic body includes a first main surface and a second main surface that face in a first direction, internal electrodes laminated in the first direction, and a penetrating hole that has a diameter decreasing from the first main surface toward the second main surface and includes a tapered surface, the internal electrodes being exposed on the tapered surface. The external electrode includes a first conductive layer disposed along the tapered surface, and a second conductive layer disposed along the first main surface and connected to the first conductive layer.

摘要： A multi-layer ceramic capacitor includes a ceramic body, a first external electrode, and a second external electrode. The ceramic body includes ceramic layers laminated along a first direction, first internal electrodes and second internal electrodes that are alternately disposed between the ceramic layers, a first end surface and a second end surface that are oriented in a second direction orthogonal to the first direction, and a first inner groove and a second inner groove that are respectively formed in the first end surface and the second end surface along the first direction. The first and second external electrodes respectively cover the first and second end surfaces, the first internal electrodes being drawn to the first end surface and protruding in the first inner groove, the second internal electrodes being drawn to the second end surface and protruding in the second inner groove.
