A multi-layer ceramic capacitor includes a multi-layer unit, a side margin, and a bonding unit. The multi-layer unit includes ceramic layers and internal electrodes. The ceramic layers are made of first ceramics and laminated in a first direction, the first ceramics having a first average crystal grain diameter. The internal electrodes are disposed between the ceramic layers. The side margin is made of second ceramics and covers the multi-layer unit from a second direction orthogonal to the first direction, the second ceramics having a second average crystal grain diameter. The bonding unit is made of third ceramics and disposed between the multi-layer unit and the side margin, the third ceramics having a third average crystal grain diameter that is larger than the first average crystal grain diameter and the second average crystal grain diameter.
