PROBLEM TO BE SOLVED: To provide a dielectric porcelain composition capable of being decreasing a temperature coefficient while maintaining high Q. SOLUTION: This dielectric porcelain composition is made up of MgO 61.5 to 65.0 mol % MgO, 30.5 to 32.5 mol % CiO2, 0.1 to 2.0 mol % Al2O3, 1.0 mol 3.0 mol % SrO, and 1.0 mol to 3.0 mol % ZrO2. If this is calcined above 1150 deg.C, its Q is made higher. |
