FIELD: manufacturing technology.
SUBSTANCE: liquid ejection head includes an ejection nozzle through which the liquid is ejected, a first fluid flow passage communicating with the ejection nozzle and through which the liquid flows, a second fluid flow channel that communicates with the ejection nozzle on the opposite side from the first liquid flow passage relative to the ejection nozzle and through which the liquid flows, the first electrode located in the first liquid flow channel, and the second electrode, which is located in the second fluid flow channel and together with the first electrode creates an electroosmotic flow in the liquid.
EFFECT: liquid ejection head and liquid circulation method are disclosed.
