ABSTRACT:
Provided are a liquid jet head unit, a manufacturing method thereof and a liquid jet apparatus, the liquid jet head unit being capable of preventing paper jams and deformation of a cover head, preventing a liquid from remaining on a liquid droplet ejecting surface and improving positioning accuracy of nozzle arrays and print quality. A liquid jet head unit includes: a liquid jet head220having nozzle arrays including arranged nozzle orifices which eject liquid droplets; a head case230fixed to a liquid supply port side of the liquid jet head220; a cover head240provided on a liquid droplet ejecting surface side of the liquid jet head; and a fixing plate250between the liquid jet head220and the cover head240, which has a junction252that defines exposure openings251having the nozzle orifices exposed therein and is joined to at least both ends of the nozzle arrays on the liquid droplet ejecting surface. In the liquid jet head unit, by joining the liquid droplet ejecting surface of the liquid jet head220and the fixing plate250, a plurality of the liquid jet heads220are positioned and fixed to a common fixing plate.
