Abstract: A ceramic electronic component includes a ceramic body, an inner electrode, an outer electrode, and a connecting portion. The inner electrode is disposed inside the ceramic body. The end portion of the inner electrode extends to a surface of the ceramic body. The outer electrode is disposed on the surface of the ceramic body so as to cover the end portion of the inner electrode. The outer electrode includes a resin and a metal. The connecting portion is disposed so as to extend from an inside of the outer electrode to an inside of the ceramic body. In a portion of the surface of the ceramic body on which the outer electrode is disposed, the length of the connecting portion that extends in a direction in which the inner electrode is extends about 2.4 μm or more.

Abstract: A ceramic body is prepared that includes an inner electrode disposed inside the ceramic body and in which an end portion of the inner electrode is led to a surface of the ceramic body. An electrode layer is formed on the surface of the ceramic body so as to cover the end portion of the inner electrode, the electrode layer containing a resin, a first metal filler that contains a first metal component, and a second metal filler that contains a second metal component having a higher melting point than the first metal component. A heating step of heating the electrode layer is performed to form an electrode including a metal layer that is located on the surface of the ceramic body and that contains the first and second metal components and a metal contained in the inner electrode.
