    Abstract: A multilayer ceramic electronic component includes: a ceramic body including a dielectric layer and first and second internal electrodes disposed to be alternately stacked with the dielectric layer interposed therebetween; a first external electrode; and a second external electrode. The first external electrode includes a first electrode layer disposed to be in contact with the ceramic body, and a first conductive layer disposed on the first electrode layer. The second external electrode includes a second electrode layer disposed to be in contact with the ceramic body, and a second conductive layer disposed on the second electrode layer. The first conductive layer and the second conductive layer are plating layers. The first conductive layer and the second conductive layer are porous.

    Abstract: A multilayer ceramic capacitor includes a multilayer body including first and second main surfaces, first and second side surfaces, and first and second end surfaces, first and second inner electrode layers on laminated dielectric layers and extending to the first and second end surfaces, first and second outer electrodes respectively on the first and second end surfaces, a third outer electrode on the first side surface, and a fourth outer electrode on the second side surface. The first inner electrode layers each have a first opposing portion facing the second inner electrode layers, a first extended portion extending from the first opposing portion to the first end surface, and a second extended portion extending from the first opposing portion to the second end surface. The second inner electrode layers each include first and second extension portions that are partially or entirely bent toward the second main surface.

    Abstract: When a multilayer ceramic capacitor is viewed as a section of a central portion in a width direction cut parallel or substantially parallel or substantially parallel or substantially parallel to a side surface, in an internal electrode layer in a central portion in a lamination direction and including an extremity spaced apart from an end surface, any one of five segments of the internal electrode layer that are horizontally and successively positioned from the extremity has a length greater than about 0.2 times of an average length of ten segments of the internal electrode layer that are horizontally and successively positioned in a central portion in a length direction.

    Abstract: A multilayer electronic component includes a body including a dielectric layer and first and second internal electrodes alternately disposed in a first direction with the dielectric layer interposed therebetween, and having first and second surfaces in the first direction, third and fourth surfaces in a second direction, and fifth and sixth surfaces in a third direction; side margin portions disposed on the fifth and sixth surfaces; and external electrodes disposed on the third and fourth surfaces. Side margin portions includes BaTiO3, Zn, and Zr, an amount of Zn and an amount of Zr in the side margin portions are 0.5 mol or more and 1.0 mol or less, relative to 100 mol of Ti included in the side margin portions. The amount of Zn and the amount of Zr in the side margin portions are different from an amount of Zn and an amount of Zr in the dielectric layer.

    Abstract: An electronic component includes an electronic element and an interposer board. The electronic element includes a multilayer body and external electrodes at a pair of multilayer body end surfaces of the multilayer body and connected to internal electrode layers. The interposer board includes board end surfaces, board side surfaces orthogonal to the board end surfaces, and board main surfaces orthogonal to the board end surfaces and the board side surfaces. One of the board main surfaces is located in a vicinity of the electronic element and joined with one of the multilayer body main surfaces in a vicinity of the interposer board. The interposer board is an alumina board. A mark portion is provided on one of the board main surfaces.
