1. A multilayer ceramic capacitor comprising:
a multilayer body including a plurality of laminated dielectric layers and a plurality of internal electrode layers laminated on the dielectric layers, the multilayer body further including a first main surface and a second main surface opposing each other in a height direction, a first end surface and a second end surface opposing each other in a length direction perpendicular or substantially perpendicular to the height direction, and a first lateral surface and a second lateral surface opposing each other in a width direction perpendicular or substantially perpendicular to the height direction and the length direction;
a first external electrode including a first surface portion located on the first end surface, at least one of a second surface portion located on a portion of the first main surface and a third surface portion located on a portion of the second main surface, a fourth surface portion located on a portion of the first lateral surface, and a fifth surface portion located on a portion of the second lateral surface; and
a second external electrode including a sixth surface portion located on the second end surface, at least one of a seventh surface portion located on a portion of the first main surface and an eighth surface portion located on a portion of the second main surface, a ninth surface portion located on a portion of the first lateral surface, and a tenth surface portion located on a portion of the second lateral surface; wherein
when a dimension in the length direction between the first end surface and the second end surface of the multilayer body is defined as I, a dimension in the width direction between the first lateral surface and the second lateral surface of the multilayer body is defined as w, and a dimension in the height direction between the first main surface and the second main surface of the multilayer body is defined as t, a dimensional relationship of w>l>t is satisfied;
the fourth surface portion, the fifth surface portion, the ninth surface portion, and the tenth surface portion each include an opening portion at which a surface of the multilayer body is exposed; and
at least one of the opening portion of the fourth surface portion is surrounded by the fourth surface portion, the opening portion of the fifth surface portion is surrounded by the fifth surface portion, the opening portion of the ninth surface portion is surrounded by the ninth surface portion, and the opening portion of the tenth surface portion is surrounded by the tenth surface portion.
