<P>PROBLEM TO BE SOLVED: To provide a fluid ejection head which effectively discharges bubbles stagnated inside without requiring a complicated circuit structure, and a fluid ejection device. Ž<P>SOLUTION: A recording head is provided with an ink storage chamber primarily storing ink supplied from a communication hole, a plurality of pressure chambers 44 respectively supplied with the ink stored in the ink storing camber through a plurality of second ink supplying pathways arranged in parallel each other, a plurality of vibrating parts 35 disposed at each pressure camber 44 for individually varying a pressure of each of the pressure chamber 44, and a plurality of nozzle openings 22 for individually ejecting the ink contained in each of the pressure chamber 44 on the basis of driving of each vibrating part 35, wherein a specific vibrating part 35A which is the vibrating part 35 disposed at the most remote position from the communication hole out of the vibrating parts 35 is set so as to have the largest width in the anteroposterior direction among the vibrating parts 35.
