1. A multilayer ceramic capacitor (MLCC), comprising:
a body including first dielectric layers and second dielectric layers, the body including a first surface and a second surface opposing each other in a first direction along which the first and second dielectric layers are stacked, a third surface and a fourth surface connected to the first surface and the second surface and opposing each other in a second direction, and a fifth surface and a sixth surface connected to the first surface, the second surface, the third surface, and the fourth surface and opposing each other in a third direction;
first internal electrodes disposed on the first dielectric layers, connected to the third surface, the fifth surface, and the sixth surface, and spaced apart from the fourth surface by first spaces;
second internal electrodes disposed on the second dielectric layers to oppose the first internal electrodes with the first dielectric layers or the second dielectric layers interposed therebetween, connected to the fourth surface, the fifth surface, and the sixth surface, and spaced apart from the third surface by second spaces;
first dielectric patterns disposed in at least portions of the first spaces to contact respective side surfaces of the first internal electrodes, and contacting the fourth surface;
second dielectric patterns disposed in at least portions of the second spaces to contact respective side surfaces of the second internal electrodes, and contacting the third surface;
lateral insulating layers disposed on the fifth surface and the sixth surface of the body; and
a first external electrode and a second external electrode disposed on the third surface and the fourth surface and connected to the first internal electrodes and the second internal electrodes, respectively,
wherein a deformation angle of the first internal electrodes is 15° or lower, the deformation angle being an angle of each portion of the first internal electrodes exposed to the third surface inclined with respect to the second surface,
a thickness, in the first direction, of a central portion of one of the first dielectric patterns in the second direction is greater than a thickness, in the first direction, of a central portion of one of the first internal electrodes in the second direction, and
a thickness, in the first direction, of a central portion of one of the second dielectric patterns in the second direction is greater than a thickness, in the first direction, of a central portion of one of the second internal electrodes in the second direction.
