    摘要: A laminate type ceramic electronic component includes a thick film resistor and an overcoat layer so as to prevent defects such as delamination from being caused and to prevent the thick film resistor from being cracked after laser trimming, even when a method is adopted in which an unfired composite laminate is subjected to firing in such a way that an unfired ceramic laminate, an unfired thick film resistor, and an unfired overcoat layer are each integrally sintered. The unfired overcoat layer includes a glass ceramic material containing a ceramic and glass having substantially the same constituents and compositional ratio as those of the glass contained in the unfired ceramic layer. The respective glass ceramic materials constituting the unfired ceramic layer and the unfired overcoat layer are adjusted so that the ratio of a crystalline phase with a smaller coefficient of thermal expansion than the coefficient of thermal expansion of the fired ceramic layer is higher in the overcoat layer than in the ceramic layer.

    摘要: A laminate includes base material layers and interlayer constraining layers disposed therebetween. The base material layers are formed of a sintered body of a first powder including a glass material and a first ceramic material, and the interlayer constraining layer includes a second powder including a second ceramic material that will not be sintered at a temperature for melting the glass material, and is in such a state that the second powder adheres together by diffusion or flow of a portion of the first powder including the glass material included in the base material layer at the time of baking. The incorporated element is in such a state that an entire periphery thereof is covered with the interlayer constraining layer.
