A liquid ejection head may include a first flow channel member and a second flow channel member, wherein the first flow channel member and the second flow channel member are disposed to form a liquid supply flow channel configured to supply liquid to an ejection port, a supply and discharge flow channel communicated with a supply port and a discharge port, and a communicating flow channel configured to communicate the supply and discharge flow channel to the liquid supply flow channel. The liquid ejection head may also include a seal member which constitutes a part of the supply and discharge flow channel and connects the first flow channel member to the second flow channel member in a water-tight manner. The communicating flow channel may be communicated with the supply and discharge flow channel via a filter disposed in the interior of the second flow channel member.
