摘要:
A multilayer ceramic capacitor includes: a ceramic body having dielectric layers laminated in a thickness direction, the dielectric layers having a greater width than a length; an active layer in which capacitance is formed, by including first and second internal electrodes alternately exposed to end surfaces of the ceramic body opposite to each other in a length direction with the dielectric layer interposed therebetween; upper cover layer; lower cover layers being thicker than the upper cover layer; and first and second external electrodes, wherein, when half of thickness of the ceramic body is denoted by A, thickness of the lower cover layer is denoted by B, half of thickness of the active layer is denoted by C, and thickness of the upper cover layer is denoted by D, 1.042≤(B+C)/A≤1.537 is satisfied.
