PURPOSE:To improve the characteristic such as Q value by forming an internal pattern onto a specific dielectric ceramic material layer, laminating the layer onto a dielectric ceramic material layer and baking the laminated component at a temperature over the melting point of an inner conductor and below the boiling point. CONSTITUTION:The multi-layer ceramic component is manufactured by forming an inner conductor pattern onto a green sheet made of a dielectric ceramic material, laminating green sheets, pressing through hot press and baking the pressed sheets. In this case, the dielectric ceramic material whose sintering end temperature obtained by a thermal contraction curve at a temperature rising rate of 200 deg.C/hour is temperature over the melting point of the inner conductor. The sintering end temperature is a cross point F between tangential lines III, IV in the thermal contraction curve of the ceramic material. Thus, the structure of the inner conductor is made tight, the contact state of the conductor is improved and the Q value is enhanced. |
