LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS

摘要

A liquid ejecting head includes: a nozzle plate provided with nozzle openings; an actuator unit including a flow channel formation substrate in which pressure generation chambers are provided and piezoelectric actuators that cause a change in the pressure of the liquid within respective pressure generation chambers; a communication substrate in which communication channels that communicate between the pressure generation chambers and corresponding nozzle openings are provided; a first case member that is a frame member affixed to the communication substrate so that the actuator unit is disposed within the first case member and that, along with the actuator unit, forms a manifold that holds the liquid to be supplied to the pressure generation chambers; and a second case member that is affixed to the first case member and in which is formed an introduction channel that sends the liquid from the exterior to the manifold.

1. A liquid ejecting head comprising:
a nozzle plate made of a silicon single-crystal substrate and comprising holes; a substrate fixed to the nozzle plate and comprising flow channels in communication with the holes; a case defining a liquid holding portion in communication with the flow channels; and pressure generation units for ejecting liquid through the holes, wherein the nozzle plate is smaller than the substrate in a planar-view from ejection direction.
