Abstract: A multilayer ceramic capacitor includes a multilayer body including dielectric layers and internal electrode layers that are laminated and a pair of external electrodes electrically connected to the internal electrode layers. The multilayer body includes an effective portion, a principal surface-side outer layer between both principal surfaces and outermost surfaces of the effective portions on both principal surface sides, and an end surface-side outer layer between both end surfaces and outermost surfaces of the effective portions on both end surface sides. The principal surface-side outer layer includes a glass layer facing the effective portion. The glass layer overlaps tips of the external electrodes on a portion of both principal surfaces and a portion of both side surfaces, and the glass layer is not exposed from the effective portion at both end surfaces.

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.
