<P>PROBLEM TO BE SOLVED: To provide an inkjet head of an ink circulation type in which the blockage of circulation of an ink in a restrictor section is inhibited. <P>SOLUTION: The inkjet head includes: an ink pressure chamber having two or more nozzles for discharging an ink droplet; a supplying channel in which an ink supplied to the ink pressure chamber flows; a discharge channel in which an ink ejected from the ink pressure chamber flows; and a piezoelectric element which applies pressure to an ink in the ink pressure chamber. In this case, the ink pressure chamber and the supplying channel communicate together through a restrictor section A, and the restrictor section A is made to produce an electro wetting effect by applying an electric field. <P>COPYRIGHT: (C)2012,JPO&INPIT |
