1. A multilayer ceramic capacitor comprising: a multilayer body; two external electrodes; and two wall portions; wherein the multilayer body includes: a multilayer main body including an inner layer portion including a plurality of dielectric layers and a plurality of internal electrode layers alternately stacked, and two outer layer portions respectively on opposite sides of the inner layer portion in a stacking direction; two side gap portions on opposite sides of the multilayer main body in a width direction intersecting the stacking direction; two main surfaces on opposite sides in the stacking direction; two side surfaces on opposite sides in the width direction; and two end surfaces on opposite sides in a length direction intersecting the stacking direction and the width direction; the two external electrodes are each provided at one of the two end surfaces of the multilayer body, and each extending from the one of the two end surfaces to a portion of the main surface; the two wall portions respectively cover outermost surfaces of portions of the external electrodes provided at the two end surfaces, and each includes a protruding portion that protrudes beyond an outermost surface of a portion of the external electrodes provided at the main surface; and at least a portion of the outermost surface of the portion of the external electrodes provided at the main surface is exposed from the wall portions when viewed from one of the two main surfaces in the stacking direction, wherein the two wall portions are made of an insulating material.
