(57) Abstract With the silver the heating possible are low at low sintering temperature loss piezoelectric ceramic constituent and the manner which produces that are offered. The constituent is 2 original piezoelectric ceramic constituents which consist of the principal constituent which features 99.5 percentages by weight from 95.0 of the systems which are displayed general expression, Pb (Zr _xTi1-x) O by₃ +yMnO2 (being in 0x1.0 formula and 0.1y1.0wt.%,). In addition as for that constituent, include also the additive of 5.0 percentages by weight from 0.5 where it is displayed general expression wB₂ O₃ xBi₂ O by₃ yMeO zCuO (in formula, w, x, y and z to be weight percentage of the respective component, it is w+x+y+z=1,). In the constituent, Me is one of the metal which are chosen from the group which consists of Ca, Sr, Ba and Zn, is 0.01w0.15wt.%, 0x0.80.wt%, 0y0.60wt.% and 0z0.55wt.%. As for the piezoelectric ceramic constituent, when with that being heated at sintering temperature of approximately 900, it does not react with silver electrode formation to remarkable.
