Abstract
A method of manufacturing an orientation film which method is suitable for manufacturing an orientation film containing a ceramic at low cost. The method includes the steps of: (a) forming a film containing a piezoelectric ceramic on a seed substrate in which crystal orientation is controlled at least on a surface thereof by using an aerosol deposition method of injecting powder toward a substrate and depositing the powder on the substrate; and (b) heat-treating the ceramic film formed at step (a) to form an orientation film in which crystal grains contained in the ceramic film is oriented.
