LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS |
摘要 |
A liquid ejecting head that includes a fluid channel formation substrate and pressure generation units. The fluid channel formation substrate is made of a silicon single crystal substrate having a crystal face orientation of. The fluid channel formation substrate has a plurality of separate flow channels that include at least pressure generation chambers demarcated by partition walls, each of the pressure generation chambers being in communication with a nozzle opening that ejects liquid drops. The fluid channel formation substrate further has a communication portion that is in communication with each of the separate flow channels. The pressure generation units are provided so as to correspond to the pressure generation chambers and generate a pressure change in the pressure generation chambers so as to cause ejection of liquid drops. |
