Claim:
1. A ceramic electronic component comprising: a ceramic element including a first principal surface, a second principal surface opposite to the first principal surface, and a plurality of ceramic layers arranged in a stacking direction; at least one first inner electrode disposed inside the ceramic element and extending to the first principal surface of the ceramic element, but not extending to the second principal surface of the ceramic element that is opposed to the first principal surface; a second inner electrode disposed inside the ceramic element, facing the at least one first inner electrode, and extending to the second principal surface of the ceramic element; an outer electrode arranged on the first principal surface of the ceramic element, connected to the at least one first inner electrode, and including a plated film directly connected to the at least one inner electrode; a first auxiliary electrode disposed inside the ceramic element and extending to the first principal surface of the ceramic element; and a second auxiliary electrode disposed inside the ceramic element and extending to the second principal surface of the ceramic element; wherein the first and second auxiliary electrodes are respectively exposed at the first principal surface and the second principal surface of the ceramic element; the at least one first inner electrode extends along a first direction on the first principal surface; the first auxiliary electrode extends outward from a region where the at least one first inner electrode is disposed in the first direction on the first principal surface; a portion of the first auxiliary electrode that is exposed at the first principal surface extends farther outward in the first direction from a region where a portion of the second inner electrode that is exposed at the second principal surface is disposed; the second inner electrode is disposed on a same layer of the plurality of ceramic layers as the first auxiliary electrode; the first auxiliary electrode crosses a center point of the first principal surface in the first direction; the outer electrode covers the at least one first inner electrode and the first auxiliary electrode; each of the at least one first inner electrode and the second inner electrode is a split inner electrode; third auxiliary electrodes are arranged at an outermost portion of the ceramic element in the stacking direction; the third auxiliary electrodes extend to at least a center point of the ceramic element in a direction perpendicular to the first principal surface and the second principal surface of the ceramic element; the third auxiliary electrodes are exposed at the first principal surface of the ceramic element; the third auxiliary electrodes extend along the first direction on the first principal surface; and the portion of the first auxiliary electrode that is exposed at the first principal surface extends farther outward in the first direction from a region where a portion of the third auxiliary electrode that is exposed at the first principal surface is disposed.
