摘要： An external electrode is formed on an outer surface of a ceramic molded product. The external electrode consists of an inner layer and an outer layer. The inner layer is composed of conductive material. The outer layer is composed of conductive material and glass material. In a process for producing the ceramic molded product, first, by molding a ceramic material a molded product is formed. On outer surfaces of the molded product, a conductive paste containing copper or the like is coated. Furthermore, on the conductive paste, a conductive paste containing a glass frit is coated. By baking the molded product onto which these two kinds of conductive paste are coated, ceramic electronic parts having an external electrode of 2-layer structure is obtained.
