Abstract
A method for producing a piezoelectric actuator having a diffusion-preventive layer and a piezoelectric layer stacked on a vibration plate includes providing the vibration plate having a surface on which a groove is formed; and blowing an aerosol containing ceramics particles toward an area, on the surface of the vibration plate, in which the groove is formed from a first direction and a second direction different from the first direction by using an aerosol deposition method to form the diffusion-preventive layer on the vibration plate. The aerosol is blown toward the vibration plate in the first and second directions. Therefore, the material particles contained in the aerosol can be collided with the inner walls of the groove formed on the vibration plate as well, and thus the diffusion-preventive layer can be formed on the vibration plate without causing any unevenness.
