Method for manufacturing piezoelectric/electrostrictive element

摘要

A method is provided for manufacturing a piezoelectric/electrostrictive element that includes a piezoelectric/electrostrictive body containing an alkali metal or alkaline-earth metal and that exhibits stable electrical characteristics without variation. The method includes the step of firing the piezoelectric/electrostrictive body and the step of washing a piezoelectric/electrostrictive element including the piezoelectric/electrostrictive body with an acidic solution or pure water. The step of washing is performed at least once after the step of firing.
