    Abstract: A multilayer ceramic capacitor includes a multilayer body including first and second main surfaces, first and second side surfaces, and first and second end surfaces, first and second inner electrode layers on laminated dielectric layers and extending to the first and second end surfaces, first and second outer electrodes respectively on the first and second end surfaces, a third outer electrode on the first side surface, and a fourth outer electrode on the second side surface. The first inner electrode layers each have a first opposing portion facing the second inner electrode layers, a first extended portion extending from the first opposing portion to the first end surface, and a second extended portion extending from the first opposing portion to the second end surface. The second inner electrode layers each include first and second extension portions that are partially or entirely bent toward the second main surface.

    Abstract: A multilayer ceramic capacitor includes a multilayer body in which dielectric layers are laminated, first and second internal electrode layers extending to both end surfaces of the multilayer body, first and second external electrodes connected to the first internal electrode layer and disposed on both end surfaces, and third and fourth external electrodes connected to the second internal electrode layer and disposed on both side surfaces. A number of the first internal electrode layers is greater than a number of the second internal electrode layers, and at least two first internal electrode layers are continuously laminated. In the first internal electrode layer, a recess is provided so as not to overlap the third and fourth external electrodes on a portion of both principal surfaces when the multilayer ceramic capacitor is viewed from a height direction.
