Abstract: A plurality of dielectric layers containing one of CaZrO3 and SrZrO3 and a plurality of internal electrodes containing Ni are alternately disposed in a second direction. The plurality of internal electrodes includes a plurality of first internal electrodes and a plurality of second internal electrodes. Each of first connecting portions of the first internal electrodes includes a first end portion connected to a first terminal electrode. Each of second connecting portions of the second internal electrodes includes a second end portion connected to a second terminal electrode. The first end portions of the first connecting portions adjacent to each other in the second direction are located not to overlap with each other when viewed from the second direction. The second end portions of the second connecting portions adjacent to each other in the second direction are located not to overlap with each other when viewed from the second direction.

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)
