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.

摘要： A branch filter which is used for mobile communication such as a portable telephone and the purpose of the invention is that a band separates two bands with a simple construction in such a way that mutual influence between both the bands is provided. An inductor (105) which is a 1st matching circuit is connected between a single-pole π-type 3-stage low-pass filter (115) and a common terminal (113), and a capacitor (106A) which is a 2nd matching circuit is connected between a single-pole band-pass filter (116) and the common terminal (113). Thus the mutual influence between both the bands is eliminated, and harmonic components are sufficiently attenuated.
