Abstract
A piezoelectric thin film contains potassium sodium niobate represented by general formula (KNa)NbOand CaTiO, wherein the lattice spacing calculated from the diffraction peak of the (001) plane in an X-ray diffraction profile of the piezoelectric thin film is 3.975 Å or less, and the ratio I/Iof the diffraction peak intensity Iof the (101) plane to the diffraction peak intensity Iof the (001) plane in the X-ray diffraction profile of the piezoelectric thin filmsatisfies the relationship log(I/I)≤−2.10.
