Abstract
A multilayer capacitor includes a body including a plurality of dielectric layers, an active region and upper and lower cover regions; first and second internal electrodes disposed with the dielectric layer interposed therebetween in the active region to be alternately exposed through both end surfaces of the body; and first and second external electrodes disposed on both ends of the body and connected to the first and second internal electrodes, respectively. The body further includes a buffer layer including first and second dummy electrodes disposed on a lower surface of the lower cover region to be spaced apart from each other in a length direction of the body, and a groove is recessed in a lower surface of the buffer layer.

A multilayer capacitor, comprising:
- a body comprising a plurality of dielectric layers laminated therein, an active region and upper and lower cover regions;
- first and second internal electrodes disposed with the dielectric layer interposed therebetween in the active region to be alternately exposed through both end surfaces of the body;
- and
- first and second external electrodes disposed on both ends of the body and connected to the first and second internal electrodes, respectively,
- wherein the body further comprises a buffer layer comprising first and second dummy electrodes disposed on a lower surface of the lower cover region to be spaced apart from each other in a length direction of the body, and
- a groove is recessed in a lower surface of the buffer layer so as to overlap at least one of the first dummy electrodes or the second dummy electrodes in the length direction.
