<P>PROBLEM TO BE SOLVED: To provide an inkjet head configured to have high resolution and to eject a fixed amount of ink from a nozzle of each ink chamber. <P>SOLUTION: The inkjet head includes: an ink supply flow channel; ink chamber groups which are alternately disposed on both-side parts of the ink supply flow channel and has two or more ink chambers; and an actuator disposed in each of the ink chambers; wherein each of the ink chamber groups has two or more ink chamber sequences in parallel with each other, and two or more nozzle sequences in parallel with each other, and in each of the ink chamber groups, each of the ink chambers in the ink chamber groups communicates with the adjacent ink chamber. When the ink chamber sequence closest to the ink supply flow channel is a first ink chamber sequence, and the ink chamber sequence farthest away from the ink supply flow channel is an n-th ink chamber sequence, the number of the ink chambers in the first ink chamber sequence is greater than the number of the ink chambers in the n-th ink chamber sequence. <P>COPYRIGHT: (C)2012,JPO&INPIT |
