LIQUID EJECTING HEAD, LIQUID EJECTING APPARATUS, AND LIQUID EJECTING HEAD MANUFACTURING METHOD |
| 摘要 |
A liquid ejecting head includes a pressure chamber formation substrate having a pressure chamber formed therein, a flow path formation substrate that is connected to the pressure chamber formation substrate, and that has a flow path in communication with the pressure chamber formed in a state penetrating through the flow path formation substrate in a thickness direction thereof, and a nozzle plate that is connected to the flow path formation substrate on an opposite side to the pressure chamber formation substrate, and that has a nozzle in communication with the flow path opened therein. The flow path formation substrate is configured from a single substrate, and an opening area on a pressure chamber side of the flow path is formed wider than an opening area on a nozzle side of the flow path. |
