摘要:
A ceramic element, including: a ceramic body having an internal electrode layer and a ceramic layer; an external electrode having a base electrode which is provided on the outside of the ceramic body so as to be electrically connected with the internal electrode layer, and a plating layer covering the outer surface of the base electrode; and a protective layer for covering at least a portion of the outer surface of the ceramic layer other than the portion covered by the external electrode, wherein the protective layer includes a first layer that is an insulating layer containing an insulating oxide, and a second layer that is an insulating layer containing the same insulating oxide as the first layer and an element that is the same as at least one of elements forming the ceramic layer, and the first layer and second layer are formed in that order from the inside.
