Abstract:
1. A laminated ceramic electronic component comprising: a component main body having a rectangular parallelepiped shape or a substantially rectangular parallelepiped shape including an LW surface defined by a length dimension L and a width dimension W, an LT surface defined by the length dimension L and a thickness dimension T, and a WT surface defined by the width dimension W and the thickness dimension T, the component main body having a stack structure including a plurality of ceramic layers extending in the direction of the LW surface and stacked in the thickness direction and a plurality of internal electrodes arranged along interfaces between the ceramic layers and including exposed ends that are exposed at the WT surface; and a plating film provided directly on at least the WT surface so as to electrically connect the respective exposed ends of the plurality of internal electrodes to each other; wherein the component main body further includes an internal dummy electrode with an exposed end exposed around a region where the exposed ends of the plurality of internal electrodes are distributed in the WT surface, and the internal dummy electrode includes two LW-direction sections extending parallel or substantially parallel to each other in a direction along the LW surface, and two LT-direction sections extending parallel or substantially parallel to each other in a direction along the LT surface, and the plating film is disposed directly over at least the exposed end of the internal dummy electrode.
