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 first external electrode and pair of second external electrodes, which is located closest to a first principal surface, is located closer to the first principal surface than an end of the pair of insulating coating portions, which is located closest to the first principal surface.

Abstract: In a laminated ceramic electronic component, a side-surface outer electrode includes a first electrode portion including side-surface electrode portions located on first and second side surfaces and wrap-around electrode portions arranged to extend around from the side-surface electrode portions of the first electrode portion to portions of third and fourth side surfaces; and a second electrode portion including side-surface electrode portions located on the third and fourth side surfaces and wrap-around electrode portions arranged to extend around from the side-surface electrode portions of the second electrode portion to portions of the first and second side surfaces. The wrap-around electrode portions of the second electrode portion reach regions covering portions of outermost inner electrodes located at an outermost side portion among inner electrodes, which portions are exposed in the first and second side surfaces.

Abstract: A series of electronic components stored in a tape include a plurality of electronic components each arranged such that a first main surface faces a bottom surface of a cavity. In each electronic component, on a first side surface, a thickness in a width direction of a first terminal electrode at a first main surface side is smaller than a thickness in the width direction of the first terminal electrode at a second main surface side, and on a second side surface, a thickness in the width direction of a second terminal electrode at the first main surface side is smaller than a thickness in the width direction of the second terminal electrode at the second main surface side.
