ABSTRACT:
A liquid jet head includes head modules each having a nozzle plate with a nozzle orifice and a passage-forming substrate having a pressure-generating chamber. The chamber communicates with the associated nozzle orifice and is pressurized by the pressure generating element so as to eject droplets. A head case is placed at the side of the passage-forming substrate opposite to the nozzle plate and has flow paths for providing a liquid to the pressure-generating chambers. The liquid jet head includes a fixing plate that has openings through which the nozzle orifices are exposed and carries the head modules positioned thereon. A connecting member is connected to the surface of the head module adjacent to the head case and has flow paths which communicate with the pressure-generating chambers. A reinforced portion made of an adhesive filling a clearance is positioned between adjacent head modules fixed to the fixing plate.
