1. A multilayer capacitor, comprising:
a body including a plurality of dielectric layers and a plurality of internal electrodes stacked with a dielectric layer interposed therebetween; and
external electrodes disposed externally on the body and connected to the internal electrodes;
wherein the body has a first surface and a second surface exposing the plurality of internal electrodes from the body and opposing each other in a first direction, a third surface and a fourth surface opposing each other in a second direction, which is a stacking direction of the plurality of dielectric layers, and a fifth surface and a sixth surface opposing each other in a third direction perpendicular to the first and second directions,
wherein a length of at least a portion of the plurality of internal electrodes in the third direction in an intermediate region of the body in the first direction is greater than a length of the first surface or the second surface of the body in the third direction,
wherein the plurality of internal electrodes have a bottleneck structure between the intermediate region and at least one of the first and second surfaces,
wherein the bottleneck structure has a recessed portion recessed into an inner portion of the body in the third direction, and
wherein the internal electrodes are connected to the external electrodes at the first and second surfaces of the body, respectively.
