Abstract: A multilayer ceramic capacitor includes a multilayer body including dielectric layers and internal electrode layers alternately laminated, and external electrodes each on a corresponding one of two end surfaces opposed to each other in a length direction perpendicular or substantially perpendicular to a lamination direction of the multilayer body. The external electrodes are each connected to the internal electrode layers. Each of the external electrodes includes a stack including a base electrode layer on a corresponding one of the two end surfaces, a Ni plated layer on the base electrode layer, and a Sn plated layer on the Ni plated layer. Each of the external electrodes includes a region in which Sn is deposited between the base electrode layer and the Ni plated layer.
