Liquid composition for forming piezoelectric film and method for forming piezoelectric film in which said liquid composition is used

Abstract

A liquid composition for forming a piezoelectric film formed of a metal oxide including at least Bi, Na, and Ti. A raw material of the Na is a sodium alkoxide, a raw material of the Ti is a titanium alkoxide, a diol and an amine-based stabilizer are included, and a molar ratio of the amine-based stabilizer with respect to the titanium alkoxide (titanium alkoxide:amine-based stabilizer) is 1:0.5 to 1:4. It is preferable that the metal oxide is included as 4% by mass to 20% by mass with respect to 100% by mass of the liquid composition.

Dependencies are inferred from the claim text.
