Abstract: A multi-layer ceramic electronic component includes a multi-layer unit and a side margin. The multi-layer unit includes a capacitance forming unit, a cover, and a side surface. The capacitance forming unit includes ceramic layers that are laminated in a first direction and contain boron, and internal electrodes disposed between the ceramic layers. The cover covers the capacitance forming unit in the first direction. The side surface faces in a second direction orthogonal to the first direction. The side margin covers the side surface in the second direction and has a lower boron concentration than a boron concentration of the ceramic layers.

Abstract: A multi-layer ceramic capacitor includes a multi-layer unit, a side margin, and a bonding unit. The multi-layer unit includes ceramic layers laminated in a first direction, and internal electrodes disposed between the ceramic layers and mainly containing nickel. The side margin covers the multi-layer unit from a second direction orthogonal to the first direction. The bonding unit is disposed between the multi-layer unit and the side margin and has a higher concentration of magnesium than the ceramic layers and the side margin.

Abstract: In an embodiment, a multilayer ceramic capacitor 10 has a capacitor body comprising a capacitive part 11a constituted by multiple internal electrode layers 11a1 that are stacked with dielectric layers 11a2 in between, as well as dielectric cover parts 11b that respectively cover both sides of the capacitive part 11a in the stacking direction. Also, the dielectric layers 11a2 of the capacitive part 11a, and the dielectric cover parts 11b, contain elemental manganese, and the elemental manganese is distributed in such a way that its quantity gradually decreases in the depth direction from the exterior faces of the dielectric cover parts 11b toward the center of the dielectric layers 11a2 of the capacitive part 11a.
