PURPOSE:To provide a dielectric porcelain composition for temperature compensation of excellent characteristic by sintering, allowing no reduction, at a low temperature of 1050 deg.C or less in a neutral or reductive environment of low oxygen partial pressure. CONSTITUTION:A dielectric porcelain composition for temperature compensation contains 22-43 parts by weight of TiO2, 38-58 parts by weight of ZrO2, and 9-26 parts by weight of SnO2 as a main component, and contains 5-35 parts by weight of a metallic oxide including at least one kind of the metallic oxide selected from B2O3, SiO2, and LiO2 as a sub-component which is added to 100 parts by weight of main component. The dielectric porcelain composition has 50ppm/ deg.C or less of temperature coefficient of dielectric constant in absolute value 2500 or more of Q value at 1MHz, and 1X10<12>OMEGAcm or more of specific resistance value at 20 deg.C. |
