Abstract
An electronic part is made from a laminated object including stacked abutting ceramic green sheets each carrying an electrically conductive paste having a contact portion in proximity to an edge of the sheet. The laminated object is fired to form a laminated body including ceramic insulator layers abutting electrically conductive internal electrode layers including contact segments in proximity to a side of the object. The body is then processed so the contact segments are exposed on the side of the object. Then an external electrode is formed on the polished body where the contact segment is exposed by using a dry process so the external electrode and the contact segment abut to establish an electric contact between the external electrode and the contact segments. The firing step causes the paste to move relative to the edges of the sheets so the contact segments are displaced relative to the edges of the sheets. The processing step results in a reduction of the displacement of the contact segments relative to the edges of the sheets so the contact segments are displaced relative to the edges of the sheets by a distance to provide an anchoring effect for the external electrode when it is formed by the dry process.
