Abstract: A multilayer ceramic capacitor includes an inner layer portion including a first-main-surface-side region, a second-main-surface-side region, and a central region between the first-main-surface-side region and the second-main-surface-side region. In the central region, dielectric layers each between internal electrodes adjacent to each other in a lamination direction and exposed at a same surfaces are in contact with the external electrode at contact portions, and an average of thicknesses of the dielectric layers at the contact portions is referred to as an average thickness Lc. In at least one of the first-main-surface-side region or the second-main-surface-side region, dielectric layers each between internal electrodes adjacent to each other in the lamination direction and exposed at the same surface are in contact with the external electrodes at contact portions, and a thickness of the dielectric layer at each contact portion is referred to as a thickness Ls and Ls

Abstract: A multilayer ceramic capacitor includes first and second internal electrode layers extending in a length direction and a width direction. Coverage ratios in regions R11 and R12 are higher than a coverage ratio in a region R15, and/or coverage ratios in regions R13 and R14 are higher than the coverage ratio in the region R15.

Abstract: A three-terminal multilayer ceramic capacitor includes a first internal electrode layer including a first counter electrode portion opposite to a second internal electrode layer, a first drawn electrode portion extending from the first counter electrode portion to a first end surface, and a second drawn electrode portion extending from the first counter electrode portion to a second end surface, the second internal electrode layer includes a second counter electrode portion opposite to the first internal electrode layer, a third drawn electrode portion extending from the second counter electrode portion to a first side surface, and a fourth drawn electrode portion extending from the second counter electrode portion to a second side surface. The first drawn electrode portion is bent and faces a first or second principal surface. The second drawn electrode portion is bent and faces the first or second principal surface.

Abstract: In a multilayer capacitor, both a minimum distance in a thickness direction between a first effective portion of a first inner electrode and a second main surface and a minimum distance in the thickness direction between a second effective portion of a second inner electrode and the second main surface are shorter than any of a dimension in the thickness direction of a first extending portion of the first inner electrode, a dimension in the thickness direction of a second extending portion of the first inner electrode and a dimension in the thickness direction of the third extending portion of the second inner electrode.
