Abstract
A cover member is fixed to a head chip in an area in the vicinity of a nozzle plate but does not constitute a communication path, and thus causes no liquid leakage. The head chip discharges droplets of a discharge liquid that is supplied via the communication path which is formed from nozzles thereof without depending on the cover member. A surface of the nozzle plate is positioned on a side further apart from a printing medium than from a surface of the cover member and is surrounded. As a result, abutting of the printing medium against a side surface of the nozzle plate is avoided.
