Abstract: A multilayer ceramic capacitor includes a multilayer body including ceramic layers and internal electrode layers laminated therein, a pair of external electrodes electrically connected to the internal electrode layers and provided on two end surfaces of the multilayer body. The pair of external electrodes each include a base electrode layer including a metal component, an electrically conductive resin layer on the base electrode layer and including a thermosetting resin and a metal component, and a Ni-plated layer on the electrically conductive layer. A stress of about −150 MPa or more and about 50 MPa or less is applied to the Ni-plated layer, and an end portion of the Ni-plated layer being in contact with the multilayer body.
