Patent ID: 7901729

Claim:
A method of manufacturing a piezoelectric/electrostrictive device having a piezoelectric/electrostrictive body and an electrode electrically connected to the piezoelectric/electrostrictive body, the method comprising the steps of: mixing and sintering first particles containing, as a major component, a piezoelectric/electrostrictive porcelain composition component including a PbMg 1/3 Nb 2/3 O 3 —PbZrO 3 —PbTiO 3 ternary solid solution system composition and NiO or including a Pb(Mg, Ni) 1/3 Nb 2/3 O 3 —PbZrO 3 —PbTiO 3 ternary solid solution system composition, with lead germanate particles, to thereby form the piezoelectric/electrostrictive body.
