Abstract:
1. A multilayer ceramic capacitor comprising: a ceramic body having first and second side surfaces facing each other, and third and fourth end surfaces connecting the first and second side surfaces; a plurality of internal electrodes formed in the ceramic body and having one ends thereof exposed to the third end surface or the fourth end surface; and a first side margin part and a second side margin part formed such that an average thickness thereof from the first and second side surfaces to edges of the internal electrodes is 18 μm or less, and wherein the ceramic body includes an effective layer contributing to capacitance formation and a cover layer provided on at least one of an upper portion and a lower portion of the effective layer, and when an average grain size of dielectric grains in the first side margin part and the second side margin part is defined by Gw, an average grain size of dielectric grains in the cover layer is defined by Gt, and an average grain size of dielectric grains in the effective layer is defined by Ga, Gw<Gt<Ga is satisfied.
