Abstract: An element body of a multilayer capacitor has a plurality of first electrodes and a plurality of second electrodes. At least one of the first electrodes is curved such that a first main body portion is located on an outer side of a first extending portion in a first direction, and at least one of the second electrodes is curved such that a second main body portion is located on an outer side of a second extending portion in the first direction. The following expressions (1) to (6) are satisfied for lengths L0 to L4 in a second direction and distances TL1 to TL3 between main surfaces. 0.03≤L1/L0≤0.1  (1) 0.1≤L2/L0≤0.25  (2) 0.75≤L3/L0≤0.9  (3) 0.9≤L4/L0≤0.97  (4) 0≤(TL1−TL2)/TL1≤0.02  (5) 0≤(TL1−TL3)/TL1≤0.02  (6)

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.
