PROBLEM TO BE SOLVED: To provide an ink jet recording head exhibiting excellent initial ink charging performance and bubble discharging performance in which curve is suppressed in the ink ejecting direction. SOLUTION: A nozzle section has a nozzle communicating section 22a opening to the side of an ink pressurizing chamber 14 wherein the bottom face of the ink pressurizing chamber has an inclining surface 14g becoming shallower according to the direction of ink ejection streamline, and wall surfaces 14h and 14i substantially perpendicular to the bottom face and disposed in parallel. A nozzle plate 20 and a frame 50 are bonded such that the end face of the nozzle communicating section on the side of the ink pressurizing chamber abuts on the inclining surface and the wall surface 14h.
