1. A multilayer ceramic capacitor comprising:
a multilayer body including a plurality of dielectric layers and a plurality of internal electrode layers that are stacked together in a stacking direction, a first surface and a second surface facing each other in the stacking direction, a third surface and a fourth surface facing each other in a width direction orthogonal or substantially orthogonal to the stacking direction, and a fifth surface and a sixth surface facing each other in a length direction orthogonal or substantially orthogonal to the stacking direction and the width directions; and
external electrodes respectively on the fifth surface and the sixth surface; wherein
the plurality of internal electrode layers include first internal electrode layers and second internal electrode layers, the first internal electrode layers being connected to the external electrode on the fifth surface, the second internal electrode layers being connected to the external electrode on the sixth surface;
the multilayer body includes an inner layer portion including the plurality of the internal electrode layers opposed to each other in the stacking direction with one of the dielectric layers interposed therebetween, and outer layer portions sandwiching the inner layer portion therebetween in the stacking direction;
the inner layer portion includes an electrode opposing portion and gap portions, the electrode opposing portion being where the first internal electrode layers and the second internal electrode layers face each other in the stacking direction, the gap portions each being located between the electrode opposing portion and the outer layer portions, and the fifth surface and the sixth surface in the length direction; and
the multilayer body includes conductor portions respectively provided in the outer layer portions corresponding to the gap portions in the stacking direction;
each of the conductor portions includes a plurality of conductor layers stacked in the stacking direction; and
one of the plurality of conductor layers at a middle or approximate middle of the multilayer body in the stacking direction includes at least a portion located closer to the middle or approximate middle of the multilayer body in the stacking direction than one of the plurality of internal electrode layers adjacent to one of the outer layer portions of the multilayer body in the stacking direction.
