PROBLEM TO BE SOLVED: To stabilize liquid ejection characteristics when a channel plate is formed of a thin layer.SOLUTION: In a groove 6a forming an individual liquid chamber 6, a liquid supply channel 7 and a liquid introducing part, of a channel plate 2, an island part (island protrusion part) 31 elongated in a liquid flowing direction is formed in a region of the liquid supply channel 7, so that two fluid resistance parts 7a and 7b are formed. A gradient part 32 is formed at least at an end part on the individual liquid chamber 6 side in the liquid flowing direction, of the island part 31, on a facing surface 6b side of the individual liquid chamber 6 facing a diaphragm member 3. |
