PROBLEM TO BE SOLVED: To provide a liquid jet head and a liquid jet device excellent in printing stability.SOLUTION: An ink jet head 5 comprises: a nozzle plate 50 having a plurality of first nozzle holes 51 and second nozzle holes for ejecting ink; an actuator plate 60 which is laminated on the nozzle plate 50 and in which a plurality of first channels 61 communicating with the first nozzle holes 51 and second channels 62 communicating with the second nozzle holes are each juxtaposed; an inlet side common ink chamber 81 extended along the juxtaposing direction of the channels 61 and 62 and collectively communicating with the insides of the respective channels 61 and 62; and an ink storage part 100 positioned upstream from the inlet side common ink chamber 81 in the flow direction of the ink and storing the ink. The ink storage part 100 has a flow passage cross-sectional area larger the than the inlet side common ink chamber 81, and a part of the inner surface of the ink storage part 100 is defined by a pressure cushioning part 105 which is deformable in a deflected fashion.SELECTED DRAWING: Figure 6 |
