Abstract
An element substrate has ejection ports for ejecting liquid, pressure chambers for storing the liquid to be ejected from the ejection ports, liquid supply paths for supplying liquid to the pressure chambers, and liquid recovery paths for recovering liquid from the pressure chambers. Filter chambers have respective filters for capturing foreign objects contained in liquid. Liquid is forced to flow upwardly from below relative to the filters.
