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 provided at one of two end surfaces of the multilayer body and connected to the internal electrode layers, and two interposers provided on both sides in a length direction of a surface of the capacitor main body. The two interposers each include a protrusion extending from one of the two interposers to another of the two interposers.
