    摘要: An ink jet recording head unit includes: at least one nozzle array in which a plurality of nozzle openings are arrayed; a plurality of common ink chambers, each adapted to store ink to be ejected; compliance parts provided to wall surfaces defining the common ink chambers, respectively; and a plurality of ink flow passages which supply ink from ink supplying sources through the common ink chambers to the nozzle openings. Of the plurality of the ink flow passages, an ink flow passage shorter than another ink flow passage has the compliance part of the common ink chamber, which is located at a middle of the ink flow passage and which is set smaller in comparison to the other ink flow passage.

    摘要: A piezo-electric/electrostrictive film type chip (50) includes: a ceramic substrate (70) having a spacer plate (74) having a windows-disposed pattern (100) having a plurality of window portions (75) and a thin closure plate (72) for closing the window portions (75) which is unitarily connected with the spacer plate; and a piezo-electric/electrostrictive working portion (71) having a lower electrode (81), a piezo-electric/electrostrictive layer (82), and an upper electrode (83), each being formed in the form of a layer and laminated in this order at a closure portion of the window (75) on the outer surface of the closure plate (72) by a film formation method. A pin hole (52) for positioning is formed in or near the center of gravity of the windows-disposed pattern (100). Deterioration of positional preciseness of the pin hole and a through hole of the piezo-electric/electrostrictive actuator can be minimized, and the piezo-electric/electrostrictive actuator can be unitarily connected with an ink nozzle member with high positional preciseness.
