Claim 0:
1. A multilayer ceramic capacitor comprising:
a multilayer body including a plurality of dielectric layers including a ceramic material and a plurality of internal electrode layers, the dielectric layers and the internal electrode layers being stacked together, two main surfaces facing each other in a stacking direction, two side surfaces facing each other in a width direction orthogonal or substantially orthogonal to the stacking direction, and two end surfaces facing each other in a length direction orthogonal or substantially orthogonal to the stacking direction and the width directions; and
two external electrodes respectively on the two end surfaces; wherein
the plurality of internal electrode layers include a plurality of first internal electrode layers and a plurality of second internal electrode layers alternately arranged in the stacking direction, the plurality of first internal electrode layers being connected to one of the two external electrodes and separated from another of the two external electrodes with a gap therebetween, the plurality of second internal electrode layers being connected to the another of the two external electrodes and separated from the one of the two external electrodes with a gap therebetween;
the multilayer body includes:
in the stacking direction, an inner layer portion and two outer layer portions sandwiching the inner layer portion therebetween, the inner layer portion including the plurality of the internal electrode layers and some of the plurality of the dielectric layers, the two outer layer portions including a remainder of the plurality of dielectric layers;
in the length direction, an electrode opposing portion and two gap portions, the electrode opposing portion being where the first internal electrode layers and the second internal electrode layers face each other, the two gap portions each being located between the electrode opposing portion and the one or the other of the two end surfaces of the multilayer body; and
four conductor portions respectively provided in the two outer layer portions in the two gap portions;

each of the four conductor portions includes a plurality of conductor layers stacked in the stacking direction; and
for each of the four conductor portions, one conductor layer closest to a middle in the stacking direction of the multilayer body among the plurality of conductor layers is closer to the middle in the stacking direction of the multilayer body than one internal electrode layer closest in the stacking direction to one of the main surfaces of the multilayer body among the plurality of internal electrode layers.
