1. A multilayer ceramic capacitor comprising:
a multilayer body including:
an inner layer portion including dielectric layers and internal electrode layers alternately laminated therein;
two outer layer portions respectively provided on both sides of the inner layer portion in a lamination direction; and
two side gap portions respectively provided on both side surfaces of the inner layer portion and the outer layer portions, in a width direction intersecting the lamination direction; and
external electrodes respectively provided on both end surfaces of the multilayer body in a length direction intersecting the lamination direction and the width direction, and each connected to the internal electrode layers; wherein
nickel and magnesium are segregated between the side gap portions and the outer layer portions.
