Abstract:
The invention provides a liquid ejecting head which is capable of introducing liquid from a liquid storage member to a pressure chamber through a liquid flow channel and discharging the liquid in the pressure chamber from a nozzle opening as liquid drops by an operation of pressure generating means including: a filter chamber in the middle of the liquid flow channel, the filter chamber having a diameter larger than other portions of the liquid flow channel and having a filter disposed therein for filtering the liquid in the liquid flow channel, wherein the filter chamber includes a liquid repellent area having a static contract angle with respect to liquid larger than that of the inner wall on the downstream side of the filter formed on the inner wall in the vicinity of the filter on the upstream side thereof.
