摘要： An ink-jet printer head includes a base plate having ink channels penetrating through the base plate, through which ink is supplied, a hollow heat driving section formed in the base plate and encircling an exit of the ink channels, an ink chamber barrier stacked on the base plate for serving as a side wall of an ink chamber where ink is reserved, and a nozzle plate stacked on the ink chamber barrier and having a nozzle which communicates with the ink channels and the ink chamber coaxially. Accordingly, an area occupied by the unit nozzle can be reduced, and ink flow in the ink chamber is easily controlled, thereby enhancing a printing speed and a print quality.
