Multilayer ceramic capacitor

A multilayer ceramic capacitor comprising:

• a multilayer body including a plurality of dielectric layers laminated in a lamination direction and each having an internal electrode disposed thereon, the multilayer body including two main surfaces respectively provided on both sides in the lamination direction, two lateral surfaces respectively provided on both sides in a width direction intersecting with the lamination direction, and two end surfaces respectively provided on both sides in a length direction intersecting with the lamination direction and the width direction;
• end-surface external electrodes respectively provided on the end surfaces of the multilayer body;
• and
• lateral-surface external electrodes respectively provided on the lateral surfaces of the multilayer body;
• the internal electrode including end-surface-exposure internal electrodes exposed at the end surfaces, and lateral-surfaces-exposure internal electrodes exposed at the lateral surfaces, each of the end-surface-exposure internal electrodes including a counter portion and a lead-out portion that extends from the counter portion, each of the lateral-surface-exposure internal electrodes including a counter portion and a lead-out portion that extends from the counter portion, the counter portion of the end-surface-exposure internal electrode and the counter portion of the lateral-surface-exposure internal electrode being opposed to each other;
• the dielectric layers including first dielectric layers each including the end-surface-exposure internal electrode thereon, and second dielectric layers each including the lateral-surface-exposure internal electrode thereon, the first dielectric layers and the second dielectric layers being alternately laminated with each other;
• wherein
• at least one of each first dielectric layer or each second dielectric layer includes an auxiliary internal electrode on a portion adjacent to at least one of the lateral surface or the end surface at which the internal electrode on the at least one of each first dielectric layer or each second dielectric layer is not exposed;
• the auxiliary internal electrode is spaced apart from the internal electrode on the at least one of each first dielectric layer or each second dielectric layer, is exposed at the at least one of the lateral surface or the end surface, and is opposed to the lead-out portion of the internal electrode that is different from and adjacent in the lamination direction to the internal electrode on the at least one of each first dielectric layer or each second dielectric layer;
• the auxiliary internal electrode includes a through hole which penetrates through the auxiliary internal electrode in the lamination direction and in which a same dielectric as that of the dielectric layers is provided, and the dielectric in the through hole establishes connection between the dielectric layers that are in contact with the auxiliary internal electrode and that are respectively located toward the two main surfaces.
