Abstract
Provided is a piezoelectric film that has a perovskite structure preferentially oriented to a (100) plane and that comprises a composite oxide represented by the following compositional formula: Pb[(ZrTi)Nb]Owherein 0<x<1, and 0.10≤y<0.13, in which in a case where a ratio I/Iof a diffraction peak intensity Ifrom a perovskite (200) plane with respect to a diffraction peak intensity Ifrom a perovskite (100) plane, as measured by an X-ray diffraction method, is r, and a/b is q, 0.28r+0.9≤q≤0.32r+0.95, 1.10≤q≤1.25, and r≤1.00 are satisfied.
