<P>PROBLEM TO BE SOLVED: To provide a piezoelectric film having good piezoelectric characteristics. <P>SOLUTION: The piezoelectric film 5 is represented by the general formula:A<SB>1-b</SB>B<SB>1-a</SB>X<SB>a</SB>O<SB>3</SB>. A contains Pb. B is constituted of at least one of Zr and Ti. X is constituted of at least one of V, Nb, Ta, Cr, Mo, and W. And a is in the range of 0.05≤a≤0.3, and b is in the range of 0.025≤b≤0.15. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
