Liquid ejection head

A liquid ejection head comprising:

• individual ejection units that include ejection ports that eject a liquid, pressure chambers that communicate with the ejection ports, first energy generation elements that are provided in the pressure chambers and generate heat energy for ejecting the liquid from the ejection ports, individual flow paths that communicate with the pressure chambers, and second energy generation elements that are provided in the individual flow paths and generate heat energy;
• and
• a common flow path configured to supply the liquid to the individual flow paths of the plurality of individual ejection units, wherein
• the plurality of ejection ports included in the plurality of individual ejection units form an ejection port array,
• the first energy generation elements and the second energy generation elements are disposed in a direction intersecting the ejection port array in the individual flow paths of the individual ejection units,
• the individual flow paths extend in a direction intersecting the ejection port array such that both end portions thereof are located with the ejection port array interposed therebetween, and
• the individual flow paths are provided with resistance structures that increase a flow resistance between the first energy generation elements and the second energy generation elements.
