PROBLEM TO BE SOLVED: To provide a recording head which can stably eject liquid droplets of a large ejection amount without being influenced by negative pressure variation and driving conditions of an ink supply source. SOLUTION: The inkjet recording head is equipped with a plurality of ejection ports 17 which eject ink, a plurality of liquid passages 18 which communicate with the ejection ports 17, and an energy generating means for ejecting the ink supplied to each liquid passage 17 as the liquid droplets from each ejection port 17. A dividing part 21 which divides to a plurality of channels is prepared more inside the liquid passage 18 than the ink ejection port 17 at a part within the liquid passage 18.
