1. A liquid ejecting head, comprising:
an actuator which ejects a liquid from a nozzle; and a circuit board which is electrically connected to the actuator, wherein the actuator and the circuit board are provided within a case of the liquid ejecting head, wherein the case includes
a joining portion which is provided on a second surface of an opposite side from a first surface on which the nozzle is formed and which is joined with a member which supplies the liquid, anda liquid discharge path, one end of which is open in the second surface, and another side of which extends from the second surface side to the first surface side and is open toward an exterior of the case, and wherein, while an opening of one end side of the liquid discharge path is positioned closer to the joining portion side than the circuit board side in the case, an opening of another end side of the liquid discharge path is positioned on an opposite side from the joining portion side to interpose the circuit board. |
