Abstract:
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.

Claim (Index 10):
A page wide type liquid ejection head comprising a plurality of sequentially arranged element substrates, each of the element substrates having an ejection port for ejecting liquid, a pressure chamber equipped in the inside thereof with an energy generating element which generates energy to be used for ejecting liquid, a supply flow path for supplying liquid to the pressure chamber and a recovery flow path for recovering liquid from the pressure chamber,\n wherein, in a supply flow path for supplying liquid to the element substrate, a filter chamber having a filter for catching a foreign object contained in liquid, a lower cell arranged downward relative to the filter and an upper cell arranged upward relative to the filter is provided; and liquid is forced to flow through the lower cell, the filter and the upper cell, the supply flow path for supplying liquid to the pressure chamber, the pressure chamber and the recovery flow path in the above mentioned order.
