The purpose of the present invention is to provides a multilayer ceramic condenser which is capable of suppressing the generation of cracks. A multilayer ceramic condenser (1B) includes: a multilayer unit (10); first and second outer layer units (6b1, 6b2) in the thickness direction; and first and second outer layer units (8b1, 8b2) in the width direction. The thickness t2 of the second outer layer in the thickness direction is greater than the thickness t1 of the first outer layer in the thickness direction, and the second outer layer in the thickness direction includes an inner layer (6b21) and an outer layer (6b22). A ceramic dielectric layer (9) of the outer layer has a greater composition of Si with respect to Ti than a ceramic dielectric layer of the inner layer, and the outer layer has a greater content of Si in a boundary unit (P1) interfaced with the inner layer. The thickness T1 of the multilayer unit is greater than the width W1 of the multilayer unit, and The width w1 and w2 of the first outer layer and second outer layer in the width direction are greater than the thickness t1 of the first outer layer in the thickness direction.
