LAMINATED CERAMIC ELECTRONIC COMPONENT

The present invention provides a laminated ceramic electronic component capable of improving reliability by suppressing infiltration of moisture from the outside to the inside of the laminated ceramic electronic component. The laminated ceramic electronic component includes a laminated body and external electrodes disposed on both end surfaces of the laminated body. The external electrode has a base electrode layer and a multilayer plating layer disposed on the base electrode layer, and the base electrode layer has a metal component and a ceramic component. A metal of a plating layer on the base electrode layer among the plurality of plating layers is diffused into the base electrode layer, reaches an interface of the laminate from a surface layer of the base electrode layer, and exist in an interface where metal components contained in base electrode layer are in contact with each other, an interface where the metal component contained in the base electrode layer and the ceramic component are in contact, and
