Abstract
A liquid ejection head includes a supply channel structure and a heater. The supply channel structure has a supply channel configured to allow liquid to flow therefrom to ejection channels that are configured to lead liquid to nozzles aligned in a first direction. The heater is configured to heat liquid. Assuming that a side of the liquid ejection head, in which the nozzles are provided, is defined as a lower side of the liquid ejection head, the heater is disposed above the supply channel structure.
