摘要：
PURPOSE: Provided is a composition for a ceramic filter and a resonator, which can improve a group delay characteristic and a temperature characteristic. CONSTITUTION: The composition is produced by substituting at least one or two elements selected from the group consisting of Ca, Sr, Ba for 0.1 to 9 mol% of Pb in a Pb(Zr1-ZTiz)O3, wherein z = 0.40 to 0.56, and adding MnO2 having 0.001 to 1.0 wt% of Mn, wherein the concentration of the Mn is higher at a grain boundary than a grain.
