Abstract
A liquid ejection head, a liquid supply apparatus, a liquid ejection apparatus, and a liquid supply method can enable the channel resistance and pressure loss of liquid in the liquid ejection head to be reduced to increase the speed at which liquid is supplied to the nozzles. To achieve this, an ink supply chamber is placed so as to be laminated on a main ink supply chamber. A filter interposed between the main ink supply chamber and the ink supply chamber extends along a surface substantially parallel to a nozzle arrangement plane on which a plurality of nozzles are arranged.
