Original Abstract Submitted

A piezoelectric substrate according to the present disclosure includes: a base body; an electrode formed at the base body; and a piezoelectric layer formed at the electrode and containing potassium, sodium, and niobium. A value of IRIR obtained by dividing an integrated intensity IR at a peak by an integrated intensity IR at a peak when a surface of the piezoelectric layer is measured by Fourier transform infrared spectroscopy, is less than 0.086. Here, the peak has a strongest area intensity among peaks detected at wavenumbers of 475 cmto 700 cm, and the peak has an area intensity that is a sum of area intensities of peaks detected at wavenumbers of 1200 cmto 1645 cm.
