1. A multilayer ceramic capacitor comprising:
a multilayer body that includes a plurality of laminated dielectric layers and a plurality of internal electrode layers laminated on the dielectric layers, and includes a first principal surface and a second principal surface facing each other in a multilayer direction, a first side surface and a second side surface facing each other in a width direction perpendicular or substantially perpendicular to the multilayer direction, and a first end surface and a second end surface facing each other in a length direction perpendicular or substantially perpendicular to the multilayer direction and the width direction;
a first external electrode on the first end surface;
a second external electrode on the second end surface;
a third external electrode on the first side surface; and
a fourth external electrode on the second side surface; wherein
the multilayer body includes an inner layer portion in which the plurality of internal electrode layers are opposite to each other;
the plurality of internal electrode layers include a first internal electrode layer and a second internal electrode layer;
the first internal electrode layer includes a first counter electrode portion opposite to the second internal electrode layer, a first drawn electrode portion that extends from the first counter electrode portion to the first end surface, and a second drawn electrode portion that extends from the first counter electrode portion to the second end surface;
the second internal electrode layer includes a second counter electrode portion opposite to the first internal electrode layer, a third drawn electrode portion that extends from the second counter electrode portion to the first side surface, and a fourth drawn electrode portion that extends from the second counter electrode portion to the second side surface;
the first drawn electrode portion includes a first bent portion;
the second drawn electrode portion includes a second bent portion;
a portion or an entirety of the first drawn electrode portion is bent and disposed, by the first bent portion, so as to face one of the first principal surface and the second principal surface;
a portion or an entirety of the second drawn electrode portion is bent and disposed, by the second bent portion, so as to face one of the first principal surface and the second principal surface; and
a first end of the first internal electrode layer at the first end surface is shifted from the first counter electrode portion toward a side of one of the first and second principal surfaces in the multilayer direction, and a second end of the first internal electrode layer at the second end surface is shifted from the first counter electrode portion toward the side of the one of the first and second principal surfaces in the multilayer direction.
