A method of manufacturing an ink-jet head according to the present invention includes a step of providing a vibration plate in which grooves associated with respective pressure chambers are formed on a surface of the vibration plate, and a piezoelectric layer forming step of forming a piezoelectric layer by depositing particles of a piezoelectric material on the surface of the vibration plate on an opposite side of a channel unit. Since grooves corresponding to the grooves in the vibration plate are formed also in the piezoelectric layer, it is possible to reduce a cross talk between operating sections of the piezoelectric layer. Further, chip and crack is hardly developed in the piezoelectric layer.
