ABSTRACT:
A method is provided for forming a potassium niobate thin film in which, in a process of manufacturing a surface acoustic wave element, a conductive thin film included in the surface acoustic wave element is used as an electrode for applying an electric field to the potassium niobate thin film that is to serve as the piezoelectric layer of the surface acoustic wave element to polarize it. A surface acoustic wave element, a frequency filter, a frequency oscillator, an electronic circuit, and an electronic apparatus are also provided.
