Claim 10:
11. The method of claim 10, wherein the sol solution of piezoelectric element is provided by mixing a sol solution of piezoelectric element having a final formula of Pb(Zr0.52Ti0.48)O3 with lead (II) acetate trihydrate, acetic acid, zirconium (IV) propoxide and titanium (IV) butoxide as the starting materials, wherein the lead (II) acetate trihydrate is added in at least 20% excess by mass into the acetic acid under vigorous stirring at 70° C. until the lead (II) acetate trihydrate is fully dissolved, followed by cooling to room temperature and adding zirconium (IV) propoxide and titanium (IV) butoxide dropwise into the solution of lead (II) acetate trihydrate in acetic acid under stirring, wherein ultrasonic processing is applied under said stirring.
