PROBLEM TO BE SOLVED: To adjust an ejection angle of an ejected droplet in the direction of arrangement of an ejection port without deceasing ejection efficiency, in an inkjet recording head with the micro-diameter ejection port, which has a high nozzle arrangement density. SOLUTION: A nozzle 5, which comprises a pressure generating chamber 9, a second ejection port part 11 and a first ejection port part 10, is formed on an energy generating element 1. A central axis 15 of the second ejection port part 11 is offset in the direction of the arrangement of the nozzle 6 with respect to a central axis 14 of the first ejection port part 10.
