Abstract: A multilayer ceramic electronic component includes a first external electrode and a second external electrode. The first external electrode includes a first extension portion that extends to a third side surface. The second external electrode includes a second extension portion that extends to the third side surface. When the third side surface is viewed from a direction in which the third side surface and a fourth side surface are opposed, the first extension portion and the second extension portion each include a base portion extending along an edge of the third side surface in a first direction, and protrusion portions extending from both ends of the base portion in the first direction along edges of the third side surface in the direction in which a first side surface and a second side surface are opposed.

Abstract: A multilayer ceramic electronic component includes a laminated body, a first external electrode, a pair of second external electrodes, and a pair of insulating coating portions. The pair of insulating coating portions extends in a laminating direction between each of the pair of second external electrodes and the first external electrode on a second principal surface, from the second principal surface to respective portions of a first side surface and a second side surface. As viewed from at least one direction in the laminating direction, an end of the pair of insulating coating portions, which is located closest to a first principal surface, is located closer to the first principal surface than an end of the first external electrode and pair of second external electrodes, which is located closest to the first principal surface.
