ABSTRACT:
An ink jet recording head controls an impulse force generated at the time of disappearing of a bubble while keeping an energy efficiency of ink ejection high. The ink jet recording head has a discharge port from which ink is discharged, a pressure chamber by which energy for ejection is given to ink, and a nozzle portion which makes the pressure chamber and the discharge port communicate. The nozzle portion includes a major diameter portion with a sectional area larger than an area of the discharge port, and a minor diameter portion, whose sectional area is smaller than that of the major diameter portion, along an ink ejection direction, and the minor diameter portion is provided between the major diameter portion and the pressure chamber.
