Abstract: A multilayer ceramic capacitor includes a capacitor main body including a multilayer body including dielectric layers and internal electrode layers alternately laminated, and external electrodes at two end surfaces of the multilayer body and connected to the internal electrode layers, and two interposers on a surface of the capacitor main body, and opposed and spaced apart from each other. The two interposers each include a first surface at or adjacent to the capacitor main body, and a second surface opposite to the first surface, the first and second surfaces being parallel or substantially parallel with each other, and the first surface is sloped with respect to the surface of the capacitor main body at a predetermined angle to be spaced from the surface of the capacitor main body toward a side at which the two interposers face each other.

Abstract: A multilayer ceramic capacitor includes a capacitor main body including a multilayer body including dielectric layers and internal electrode layers alternately laminated, and external electrodes each at end surfaces of the multilayer body and connected to the internal electrode layers, and two interposers on a surface in a lamination direction of the capacitor main body, and spaced apart from each other in a length direction connecting the two end surfaces and intersecting the lamination direction. The external electrodes each include a bulge portion protruding in the lamination direction on the surface of the capacitor main body. The interposers each include a recess portion on each of the end surfaces, and in a cross section extending in the lamination direction and the length direction and passing through a center in a width direction. The bulge portion is closer to the end surface in the length direction than the recess portion.
