<p>Provided is an inkjet head which suppresses generation of satellite droplets even when a nozzle having a jetting port having a diameter of 10µm or less is used. The inkjet head is provided with a nozzle having a jetting port having a diameter of 10µm or less, a pressure chamber connected to the nozzle, an inlet for introducing an ink into the pressure chamber, and an actuator for generating pressure to the ink by changing the volume of the pressure chamber. The shapes of the nozzle, the pressure chamber and the inlet are set so that an inequality of f1=f2 is satisfied, where, f1 is a number of characteristic frequency of a meniscus in the nozzle, and f2 is a number of characteristic frequency of the pressure chamber.</p> |
