More Information
Summary:A liquid ejection head includes a liquid chamber (12) configured to contain liquid to be ejected from a nozzle (18), a liquid ejection member (17) including the nozzle, and an energy generating element (13) configured to provide energy to the liquid contained in the liquid chamber. The energy generating element ejects the liquid contained in the liquid chamber from the nozzle as a liquid droplet. A depression (19) is formed on a surface of the liquid ejection member around the nozzle such that an opening of the depression has a width greater than a width of an opening of the nozzle and the nozzle is positioned at the bottom of the depression. The interior angle of the bottom corner (19a) of the depression is determined to be greater than 90 degrees.
