摘要： An inkjet head is disclosed. In accordance with an embodiment of the present invention, the ink-jet head that prevents a nozzle from being blocked by a residual ink droplet formed on the nozzle can include a head body having the nozzle formed on one surface thereof and an actuator, which provides pressure to the inside of the head body. Here, a transfer groove is formed on one surface of the head body, in which the transfer groove is separated from the nozzle to provide a path through which the residual ink droplet moves. Thus, the inkjet head can prevent the nozzle from being blocked by a residual ink droplet formed on the nozzle by use of the transfer groove, which provides a path for a residual ink droplet formed on the nozzle to escape.
