An actuator 14 is formed with a plurality of ejection channels 13 in two rows which are spaced apart from each other at a prescribed distance. A manifold 17 is joined with an inflow end surface of the actuator 14. The manifold 17 is formed with an ink supply channel 16 for supplying liquid ink from the ink cartridge to each of the ejection channels 13. The ink supply channel 16 is formed to extend along the rows of the ejection channels 13 to be opened over the inflow ends 13i of the ejection channels 13. The width of the ink supply channel 16, opened at the surface of the manifold 17 as connected to the actuator 14, is less than or equal to the distance between the outer side inner walls 51 and 51 of ejection channels 13 in the two rows.
