Claim Text:
1. A multilayer ceramic capacitor comprising: a ceramic body in which a plurality of dielectric layers are laminated; an active layer including a plurality of first and second internal electrodes formed to be alternately exposed to both end surfaces of the ceramic body with the dielectric layer interposed therebetween, and forming capacitance; an upper cover layer formed on an upper portion of the active layer; a lower cover layer formed on a lower portion of the active layer and having a thickness greater than that of the upper cover layer; and first and second external electrodes covering both end surfaces of the ceramic body, wherein when a width of an L-margin portion formed between an end portion of the internal electrode in a length direction and one end surface of the ceramic body is LM, a width of a W-margin portion formed between a side of the internal electrode in a width direction and one lateral surface of the ceramic body is WM, and a thickness of the lower cover layer is B, 0.3≦LM/B≦2.0 and 0.5≦B/WM≦5.0 are satisfied, and when half of the overall thickness of the ceramic body is A, a thickness of the lower cover layer is B, half of the overall thickness of the active layer is C, and a thickness of the upper cover layer is D, a ratio (B+C)/A by which a central portion of the active layer deviates from a central portion of the ceramic body satisfies 1.063≦(B+C)/A≦1.745.
