摘要： A method of manufacturing a liquid ejecting head that ejects a liquid supplied from a liquid storing member through a liquid supply path. The method includes positioning a filter to a first or second supply member by using positioning pins upon disposing the filter between first and second liquid supply paths. The first supply member has the first liquid supply path. The second supply member has the second liquid supply path on the side of one surface of the first supply member to communicate with the first liquid supply path. At least the first supply member and the second supply member are integrated such that a fixed portion is molded by injecting a resin material from an injection portion of a mold at a position where the first and second liquid supply paths are interposed between the positioning pins.

摘要： Provided is a liquid jet head unit and a liquid jet device which are capable of improving precision in aligning nozzle orifices and accordingly printing quality. Included are: a liquid jet head having a nozzle plate provided with nozzle rows constituted of nozzle orifices through which liquid droplets are ejected, and which are arranged side by side; a head case fixed to the liquid jet head at the side of liquid supply ports; and a cover head provided to a liquid-droplet ejecting surface of the liquid jet head. An exposed area in the nozzle plate, which area is not covered by the cover head, includes: nozzles provided respectively with water repellent films in peripheries of their nozzle orifices; and nozzles which have the same shape as the former nozzles, and which respectively have non-water repellent portions provided with no water repellent films in peripheries of their nozzle orifices.
