A multi-layer ceramic capacitor includes: a ceramic body that includes a plurality of ceramic layers laminated in one axial direction and includes polycrystal having a Perovskite structure as a main phase, the Perovskite structure containing calcium and zirconium and being expressed by a general expression ABO, the polycrystal containing silicon, boron, and lithium; first and second internal electrodes alternately disposed between the ceramic layers; a first external electrode provided on an outer surface of the ceramic body and connected to the first internal electrodes; and a second external electrode provided on the outer surface of the ceramic body and connected to the second internal electrodes, the multi-layer ceramic capacitor satisfying 0.2858V+0.4371&#x2264;C&#x2264;0.1306V+3.0391, where V (mm) represents a volume of the ceramic body, and C(atm %) represents a concentration of the lithium when a concentration of a B-site element of the main phase of the polycrystal is 100 atm %.
