Abstract: A multilayer ceramic capacitor includes a multilayer body including dielectric layers and internal electrodes alternately stacked on one another, and two external electrodes on two end surfaces of the multilayer body. The internal electrodes include first internal electrodes and second internal electrodes arranged alternately. A distance between the first internal electrodes adjacent to each other includes a distance T11 and a distance T12. The distance T11 is greater than the distance T12. A distance between the second internal electrodes adjacent to each other includes a distance T21 and a distance T22. The distance T21 is greater than the distance T22.

Abstract: A multilayer ceramic capacitor includes a multilayer body including dielectric layers and internal electrodes alternately stacked on one another, and two external electrodes respectively on two end surfaces of the multilayer body. Each of the dielectric layers includes, at a location coincident with an end portion of a respective one of the internal electrodes, a thick-walled portion thicker in a stacking direction than a portion corresponding in position to a middle portion of a main surface of the multilayer body. When viewed in the stacking direction, positions of some of the thick-walled portions of the dielectric layers are out of alignment with positions of a remainder of the thick-walled portions of the dielectric layers.

Abstract: A ceramic capacitor that has low ESL and is suitable to be built into a substrate includes a first external electrode including a first portion extending from a portion located on a first principal surface to a portion of a first end surface, a second portion extending from a portion located on a second principal surface to a portion of the first end surface, a third portion extending from a portion located on a first side surface to a portion of the first end surface, and a fourth portion extending from a portion located on a second side surface to a portion of the first end surface. The first external electrode includes an outermost layer that is a Cu plated layer.
