摘要：
Element substrate 2 has ejection ports for ejecting liquid, pressure chambers 62 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 66 for recovering liquid from the pressure chambers. The filter chambers 23 have respective filters 11 for seizing foreign objects contained in liquid. Liquid is forced to flow from downward to upward relative to the filters 11.
