1. A capacitor component comprising:
a body having a first surface and a second surface opposing each other in a first direction, third and fourth surfaces opposing each other in a stacking direction while respectively connecting the first and second surfaces to each other, and fifth and sixth surfaces opposing each other in a second direction while respectively connecting the first to fourth surfaces, and including a multilayer structure in which a plurality of dielectric layers are stacked in the stacking direction and first and second internal electrodes are alternately disposed with respective dielectric layers interposed therebetween and extending from the first surface and the second surface, respectively;
first and second metal layers covering the first surface and the second surface and connected to the first and second internal electrodes, respectively; and
first and second external electrodes covering the first and second metal layers, respectively,
wherein the first metal layer is disposed only on the first surface among the first, third and fourth surfaces,
the second metal layer is disposed only on the second surface among the second, third and fourth surfaces,
each of the first and second external electrodes extends to cover the third and fourth surfaces of the body,
each of the first and second external electrodes includes a first layer that is a sintered electrode and a second layer covering the first layers and including a plurality of layers,
on one of the third and fourth surfaces of the body, a maximum dimension, in the stacking direction, of the second layer is greater than a maximum dimension, in the stacking direction, of the first layer, and
the first layer is in contact with end portions of the first metal layer which oppose each other in the stacking direction and end portions of the first metal layer which oppose each other in the second direction.
