Abstract:
An object of the present invention is to provide an ink jet head and the like that are small, are capable of achieving a higher resolution, increasing ejection stability, and lowering production costs, and include flow paths capable of circulating ink. An ink jet head of the present invention includes: a head chip including nozzles, pressure chambers that communicate with the respective nozzles, piezoelectric elements that correspond to the respective pressure chambers, discrete circulation flow paths that branch from ink flow paths extending from inlets of the pressure chambers to outlets of the nozzles and are capable of discharging the ink in the pressure chambers, and a common circulation flow path with which at least two of the discrete circulation flow paths communicate; and a common supply liquid chamber that is provided on the upper surface of the head chip, and stores the ink to be commonly supplied to the respective pressure chambers through ink supply holes formed in the upper surface of the head chip.

Claim (Index 6):
The ink jet head according to  claim 1 , further comprising\n a first damper that is provided to face at least one of the discrete circulation flow paths and the common circulation flow path, and are capable of changing volumes of flow paths when being elastically deformed by pressure.
