Zusammenfassung:A ceramic electronic device includes an element body and an external electrode. The element body is formed by laminating a ceramic layer and an internal electrode layer. The external electrode is electrically connected to at least one end of the internal electrode layer. The external electrode includes a baked electrode layer. The baked electrode layer includes a first region and a second region. The first region is contacted with an end surface of the element body and located near a joint boundary with the element body. The second region is located outside the first region and constituting an outer surface of the baked electrode layer. The first region includes a first glass having a predetermined composition. The second region includes a second glass having a predetermined composition.
