Abstract:
1. A method of producing at least one liquid delivering apparatus which delivers a liquid from at least one liquid chamber thereof to a location outside the at least one liquid delivering apparatus, by deforming a piezoelectric element thereof provided at a location opposed to the at least one liquid chamber and thereby applying a pressure to the liquid in the at least one liquid chamber, the method comprising the steps of: stacking a first preformed sheet member having at least one opening defining the at least one liquid chamber and a second preformed sheet member covering the at least one opening, on each other, and integrating, by diffusion bonding or anode bonding, the first and second preformed sheet members with each other so as to provide an integral, stacked body; forming, of a material of the piezoelectric element, a layer on at least a portion of the second preformed sheet member of the stacked body that is opposed to the at least one opening of the first preformed sheet member of the stacked body; and annealing the layer formed on the stacked body, and thereby crystallizing the material of the layer, so as to change the layer into the piezoelectric element.
