The cavity unit has nozzle groups each of which includes at least one nozzle from which a droplet of a liquid is ejected. At least two of the nozzle groups are differentiated from each other in the cross-sectional area of the nozzles. The supply-passage forming portion integrally includes liquid supply passages that correspond to the respective nozzle groups, and are open in a same surface of the supply-passage forming portion. The filter member integrally includes filtering portions, and is closely attached to the surface of the supply-passage forming portion such that the filtering portions respectively cover openings of the passages. Each filtering portion has pores of a cross-sectional area such that a cross-sectional area of pores in one of the filtering portions, which corresponds to a first one of the at least two nozzle groups a cross-sectional area of the nozzle belonging to which is larger than that of the nozzle belonging to a second one of the at least two nozzle groups, is larger than a cross-sectional area of pores of another filtering portion corresponding to the second nozzle group.
