Claim 0:
1. A multilayer ceramic capacitor comprising:
a multilayer body including a plurality of first inner electrodes and a plurality of second inner electrodes stacked in layers and a plurality of dielectric layers each interposed between adjacent ones of the first and second inner electrodes, the multilayer body including a first outer electrode receiving portion at a first end thereof in one direction, a second outer electrode receiving portion at a second end thereof in the one direction, and a main portion between the first outer electrode receiving portion and the second outer electrode receiving portion;
a first outer electrode electrically connected to the first inner electrodes and extending over the first outer electrode receiving portion of the multilayer body; and
a second outer electrode electrically connected to the second inner electrodes and extending over the second outer electrode receiving portion of the multilayer body; wherein
a level difference exists at a boundary between the main portion and the first outer electrode receiving portion of the multilayer body and at a boundary between the main portion and the second outer electrode receiving portion of the multilayer body;
an area of a cross section at a central position of the main portion in the one direction, along a plane orthogonal to the one direction, is greater than an area of a cross section at a position of the first outer electrode and a cross section at a position of the second outer electrode along a plane orthogonal to the one direction; and
the multilayer body satisfies at least one of the following:
a cross-sectional shape of the first outer electrode receiving portion and the second outer electrode receiving portion taken along the plane orthogonal to the one direction is a circle;
a shape of each of the first outer electrode receiving portion and the second outer electrode receiving portion is cylindrical or substantially cylindrical;
each of the first outer electrode receiving portion and the second outer electrode receiving portion has an octagonal prism shape or a substantially octagonal prism shape; and
each of the cross section at the position of the first outer electrode and the cross section at the position of the second outer electrode along the plane orthogonal to the one direction is octagonal or substantially octagonal.
