A liquid ejection head includes: an ejection port; a supply section and a discharge section; a main flow channel; a supply flow channel; a filter; and a sub flow channel, one end of which is connected to a first connection position near the supply section, and the other end of which is connected to a second connection position near the discharge section, wherein the main flow channel and the sub flow channel are formed such that, in supplying the liquid from the supply section to the main flow channel at a predetermined flow rate, the higher the predetermined flow rate is, the more the ratio of a flow rate in the main flow channel from the first connection position to the second connection position to a flow rate in the sub flow channel increases.
