LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS
First Claim
1. A liquid ejecting head comprising:
- a nozzle plate provided with nozzle openings that eject a liquid;
an actuator unit including a flow channel formation substrate in which pressure generation chambers that communicate with respective nozzle openings are provided and pressure generation units that cause a change in the pressure of the liquid within respective pressure generation chambers;
a communication substrate, provided between the nozzle plate and the actuator unit, 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 part of a liquid holding portion 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 liquid holding portion.

Abstract
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.
