Abstract | PROBLEM TO BE SOLVED: To provide a print head wherein an influence on an ink to be ejected from an ejection port subsequently by an air flow generated by an ejected ink is suppressed evenly for respective ejection ports in the print head. SOLUTION: A print head 100 has an ejection port for ejecting ink. On an ejection port forming face formed with the ejection port 1, a projection 8 projecting from the ejection port forming face is formed. The projection 8 is arranged at a position where the distance from the center of the ejection port 1 is within the maximum of a diameter of a vortex core of a vortex that is formed when liquid droplets are ejected in the case that no projection is formed.
