In a method and an apparatus for ejecting liquid, the processing accuracy of an ejection unit for ejecting ink can be easily increased and the variations in the volume of ink drops, the ejection angle thereof, etc., can be reduced even when dust is mixed in ink. In addition, a reduction in an ink-supply speed at which ink is supplied to an ink ejection unit can be prevented. An ink ejection apparatus includes a plurality of heating units () provided on a base member (), ink cells for pressurizing ink with energy generated by the heating units (), and nozzles () having ejection holes for ejecting the ink which is pressurized in the ink cells. Each of the nozzles () is disposed above each of the heating units (). In addition, first open sides of the nozzles () which face the heating units () serve as ink inlets () and second open sides of the nozzles () serve as the ejection holes (), so that inner spaces of the nozzles () serve as the ink cells, the ink cells not being provided separately.

Liquid delivering device and liquid delivering method

A method of manufacturing a piezoelectric actuator, formed of multiple concave parts which are provided on one surface. First, a first sheet is formed of pliant piezoelectric materials and a second sheet is formed of pliant predetermined materials, forming an upper electrode layer formed of conduction materials on one surface of said first sheet, and forming a lower electrode layer formed of conduction materials on the other surface of said first sheet or one surface of said second sheet, wherein piezoelectric material is used as said material of the second sheet and electrode layer for polarization formed of conduction material is formed on the other surface side of said second sheet. Next, the first and second sheets are piled and densified. The first sheet is polarized in a direction of a thickness of the first sheet. In a fourth step, the upper electrode layer is patterned in order to form multiple electrodes corresponding respectively to each pressure chamber of the pressure chamber forming unit, wherein by placing a voltage between the upper electrode layer and the electrode layer for polarization, the first sheet is polarized in the direction of its thickness.
