1. A multilayer ceramic capacitor comprising:
at least one first dielectric layer including at least one first internal electrode;
at least one second dielectric layer including at least one second internal electrode; and
a multilayer body including the first dielectric layer and the second dielectric layer provided alternately therein; wherein
the multilayer body includes two main surfaces, two lateral surfaces, and two end surfaces;
the multilayer body includes an inner layer portion including the first internal electrode and the second internal electrode laminated alternately therein with the dielectric layer interposed therebetween, outer layer portions that sandwich the inner layer portion in a lamination direction and are made of a dielectric material, and side gap portions that sandwich the inner layer portion and the outer layer portions in a width direction;
the multilayer body includes a first external electrode connected to the first internal electrode and a second external electrode connected to the second internal electrode;
the first external electrode includes a main surface electrode portion provided on at least one of the two main surfaces, and a lateral surface electrode portion on one of the two lateral surfaces that is connected to at least one lateral surface side end portion of each of the first internal electrodes and covered with one of the side gap portions such that the one of the side gap portions defines an outermost surface of the multilayer ceramic capacitor at a portion where the side gap portion covers the lateral surface electrode portion; and
the one of the two lateral surfaces is flat or substantially flat.
