摘要： A method for evaluating a piezoelectric film containing a perovskite oxide containing a lead atom, a zirconium atom, and a titanium atom, and the method includes a process of irradiating the piezoelectric film with X-rays to acquire an extended X-ray absorption fine structure (EXAFS) spectrum at the L3 absorption edge of the lead atom, a process of Fourier-transforming the extended X-ray absorption fine structure (EXAFS) spectrum to acquire a radial distribution function, and a process of acquiring the intensity of a first peak having a distance from the lead atom of 1.4±0.2 Å, the intensity of a second peak having a distance from the lead atom of 2.0±0.2 Å, and the intensity of a third peak having a distance from the lead atom of 2.6±0.2 Å from the radial distribution function, and then evaluating the film quality of the piezoelectric film from a value obtained by dividing the intensity of the first peak by the intensity of the second peak and a value obtained by dividing the intensity of the first peak by the intensity of the third peak.
