1. A liquid ejecting head comprising:
a head unit in which a plurality of unit heads are arranged, the unit heads being configured to eject a liquid through a nozzle formed on a nozzle surface by using a pressure change in a pressure chamber which is generated by driving a pressure generating section; a controller that transmits a control signal for controlling driving of the pressure generating section to the head unit; and a frame on which a plurality of the head units and the controllers which correspond to the head units are fixed, wherein the frame includes a head unit fixing section in which the head units are arranged side by side with the nozzle surface being exposed and a controller fixing section which is stacked on the head unit fixing section on the side opposite to the nozzle surface and in which the controllers are arranged side by side in an arrangement direction of the head units, the controller fixing section is composed of at least two layers, and the controllers which correspond to the adjacent head units in the arrangement direction in the head unit fixing section are arranged alternately in the at least two layers in the controller fixing section. |
