The interior channel includes a portion 2246 extending toward the first face 2227 and a portion 2247 extending toward the second face 2228.

Abstract: Element substrate 2 has ejection ports for ejecting liquid, pressure chambers 62 for storing the liquid to be ejected from the ejection ports, liquid supply paths for supplying liquid to the pressure chambers and liquid recovery paths 66 for recovering liquid from the pressure chambers. The filter chambers 23 have respective filters 11 for seizing foreign objects contained in liquid. Liquid is forced to flow from downward to upward relative to the filters 11.

Abstract: A common supply channel is connected to one end of a discharge module having a discharge orifice that discharges liquid, and a common recovery channel is connected to the other end of the discharge module. A valve connecting the common supply channel and common recovery channel is provided in an adjustment channel, and is opened under a first opening pressure. A pump causes liquid to flow from the common supply channel toward the common recovery channel. Flow resistance of the common recovery channel is smaller than flow resistance of the discharge module.

Abstract: Provided is a liquid storage bottle capable of suppressing a decrease in degree of internal pressure reduction with a simple configuration. The liquid storage bottle includes: a main body portion configured to store a liquid; a nozzle portion configured to discharge the liquid stored in the main body portion; a cap mounted on the nozzle portion; a space portion formed between the nozzle portion and the cap; and a communicating portion configured to allow the space portion to communicate with outside of the liquid storage bottle. The nozzle portion includes a contact portion which comes into contact with the cap in a state in which the cap is mounted on the nozzle portion, and the communicating portion is a groove portion formed by cutting out a part of the contact portion.
