Abstract: A length in a first direction of the element body is smaller than a length in a second direction of the element body and smaller than a length in a third direction of the element body, the second direction being perpendicular to the first direction, the third direction being perpendicular to the first and second direction. Each of a first terminal electrode and a second terminal electrode includes a sintered conductor layer formed on the element body, a first plated layer formed on the sintered conductor layer, and a second plated layer formed on the first plated layer. In each of a first electrode portion disposed on a principal face and a third electrode portion disposed on a principal face, a maximum thickness of the sintered conductor layer is larger than a thickness of the first plated layer and not more than a thickness of the second plated layer.

Abstract: A ceramic electronic component includes an interior part and an exterior part. The interior part includes an interior part dielectric layer and an internal electrode layer. The exterior part includes an exterior part dielectric layer. The exterior part is positioned outside the interior part along a laminating direction thereof. The interior part dielectric layer and the exterior part dielectric layer respectively contain barium titanate as a main component. β−α≧0.20 and α/β≦0.88 are satisfied, where α mol part and β mol part are respectively an amount of a rare earth element contained in the interior and exterior part dielectric layers, provided that an amount of barium titanate contained in the interior and exterior part dielectric layers is respectively 100 mol parts in terms of BaTiO3.

Abstract: An element body includes a pair of principal surfaces, a pair of side surfaces, and another pair of side surfaces. Each of a pair of terminal electrodes includes a first electrode portion disposed on the principal surface and a second electrode portion disposed on the side surface. In the element body, a length in a direction in which the pair of principal surfaces oppose each other is smaller than a length in a direction in which the pair of side surfaces oppose each other and smaller than a length in a direction in which the other pair of side surfaces oppose each other. An arithmetic mean deviation of the surface of the first electrode portion is from 0.20 to 0.26 μm. An arithmetic mean deviation of the surface of the second electrode portion is from 0.27 to 0.38 μm.
