Abstract: PROBLEM TO BE SOLVED: To easily improve the processing accuracy of an ink ejecting part, reduce change in the ink droplet ejection amount, the ejection angle, or the like derived from dust introduction to the ink, and to prevent deterioration of the ink supply speed to the ink ejecting part. SOLUTION: An ink ejecting unit comprises a plurality of energy generating means 13 provided on a substrate member 11, an ink liquid chamber for pressuring an ink by the energy generated by the energy generating means 13, and a nozzle having an ejection opening for ejecting the ink pressured in the ink liquid chamber. The internal space of the nozzle 17 serves also as the ink liquid chamber without the need of forming an ink liquid chamber independently by disposing a nozzle 17 above the energy generating means 13, and providing the opening surface on the energy generating means 13 side of the nozzle 17 as an ink inlet opening 17b and the opening surface on the other side as an ink ejecting opening 17a.

Abstract: PROBLEM TO BE SOLVED: To realize a manufacturing method for print head in which resource efficiency can be enhanced significantly at the time of mass production. SOLUTION: In the manufacturing method for print head, a sheet of piezoelectric material is secured temporarily on one side of a substrate with reference to a positioning through hole 64H and subjected to separation machining into first shape corresponding to a piezoelectric element 55 while preventing one side of the substrate from being cut by abrasive grains being blown thereto at the time of etching. Since the substrate can be reused at the time of mass production, resource efficiency can be enhanced significantly in manufacturing a print head.

Abstract: PROBLEM TO BE SOLVED: To eject an ink drop stably outward. SOLUTION: A lower electrode is formed of a conductive material on one surface of a piezoelectric element 55 on the side of a diaphragm 54 and an upper electrode 56 is formed of a conductive material on the opposite surface of the piezoelectric element 55 while partially facing a part no recess is made in one surface of a channel plate. According to the structure, oscillation characteristics of the piezoelectric element 55 can be substantially prevented from fluctuating in a region facing the pressure chamber of the channel plate even if the upper electrode 56 is connected with a wire 62 and an ink drop can be ejected stably outward.

Abstract: PROBLEM TO BE SOLVED: To form a pressure chamber or a through hole in a channel plate finely and precisely by blowing abrasive grains of specified means grain size to the surface being machined of a matter to be machined thereby etching the surface being machined and forming a pressure chamber and a through hole in one surface of a planar member. SOLUTION: A channel plate is manufactured by making a nozzle of through hole and a through hole 50C or a recess of ink channel, e.g. a pressure chamber, in one surface 50A of a glass plate 50 by powder beam machining. In powder beam etching, abrasive grains having mean grain size of 24 μm or less are blown to the surface to be machined. An ink jet head is manufactured by pasting a diaphragm and a piezoelectric actuator comprising a piezoelectric element, while positioning, on one surface of the channel plate. According to the method, a pressure chamber and an ink channel, e.g. a nozzle, can be formed with high accuracy without causing fluctuation in the width, length or depth.
