摘要： A dielectric porcelain composition of the present invention includes a first component and second component. If the first component is represented by the general formula of xBaO-yNd 2 O 3 -zTiO 2 -wBi 2 O 3 (provided that x+y+z+w= 100), x, y, z, and w satisfy 12 ≤ x ≤ 16,12 ≤ y ≤ 16, 65 ≤ z ≤ 69, and 2 ≤ w ≤ 5, respectively. The second component includes 30 to 37 wt% of BaO, 33 to 46 wt% of SiO 2 , 8 to 12 wt% of La 2 O 3 , 3 to 7 wt% of Al 2 O 3 , 0 to 1 wt% of SrO, 0 to 10 wt% of Li 2 O, 0 to 20 wt% of ZnO, and 7 wt% or less of B 2 O 3 . The compounding ratio of the second component is between 10 wt% and 30 wt% when the sum of the first and second components is 100. In addition, 0.1 to 1 parts by weight of Li 2 O and 3 to 10 parts by weight of ZnO, relative to 100 parts by weight of the sum of the first and second components, is also contained as a third component. An average particle diameter of the dielectric mixed powder forming dielectric porcelain composition before firing is 0.9 µm or less.

摘要： It is an object of the present invention to provide a ceramic component with high reliability and accuracy in dimension in which electrical characteristics thereof are not largely deteriorated and defects such as cracks around the inner electrodes in the substrate after firing are inhibited, in a firing technique with high accuracy in dimension for sandwiching a glass ceramic laminate with heat-shrinkage inhibiting sheets and firing them. In order to achieve this object, the method of manufacturing the ceramic component of the present invention includes: a conductor printing step of applying, to a glass ceramic green sheet, conductor paste that has substantially the same sintering speed as the glass ceramic green sheet; a lamination step of laminating a plurality of the glass ceramic green sheets to form a laminate; a composite lamination step of further laminating, on at least one side of the laminate, a heat-shrinkage inhibiting green sheet based on inorganic material to form a composite laminate; a debindering step of burning out organic material from the composite laminate; a firing step of sintering the composite laminate after the removal of the organic material so that the sintering behaviors of the glass ceramic green sheets and the conductor paste match with each other; and a step of removing the inorganic material in the heat-shrinkage inhibiting green sheet.
