Zusammenfassung: | To provide a multilayer ceramic capacitor that includes a sufficient humidity resistance.SOLUTION: A multilayer ceramic capacitor comprises a pair of outer electrodes 20 that is arranged so as to cover at least a pair of end surfaces 17c to both end parts of a long direction L of a lamination body 12, and is connected to an internal electrode layer 14 of the lamination body 12. Each outer electrode 20 comprises: a first external electrode layer 21 that is contacted to the internal electrode layer 14 that covers each of end surfaces 17c; a second external electrode layer 22 that is formed onto the first external electrode layer 21; and a plating layer 23 that is formed on the second external electrode layer 22. The first external electrode layer 21 contains Ni and a dielectric particle 21b. The second external electrode layer 22 contains Cu and a glass 22b. In a boundary between the first external electrode layer 21 and the second external electrode layer 22, a metal group 24a containing at least one metal of Sn, In, Ga, Zn, Bi, Pb, Fe, V, Y, and Cu is provided.SELECTED DRAWING: Figure 3
