Abstract

The present invention, in the piezoelectric material is sintered at a low temperature of lead zirconate titanate mixed crystals based (PZT mixed crystal base), the PZT mixed crystals, substoichiometric relative stoichiometrically pure PZT mixed crystal a logical manner lead -, zirconium - and / or has a titanium content, and the PZT mixed crystals of silver, ≧ 0.005 to ≦ on the total weight of the other components of the PZT mixed crystal 0.21 material characterized in that it comprises an amount of mass%, a piezoelectric element including a piezoelectric material is sintered at the low temperature production methods as well as the PZT mixed crystal based piezoelectric material is sintered at the low temperature of the PZT mixed crystal base .
