PROBLEM TO BE SOLVED: To prevent a discharge failure of higher-density nozzle opening sections.SOLUTION: An ink jet head includes: a nozzle plate 10 including nozzle opening sections N for discharging ink to a recording medium; and head chips 110 which are provided to correspond to the nozzle opening sections N, and include pressure chambers 21 for storing ink discharging from the nozzle opening sections N and conduction paths 101 which are provided to communicate the pressure chambers 21 with the nozzle opening sections N by being joined to the nozzle plate 10. In the nozzle plate 10, a plurality of head chips 110 are provided. Alignment marks M1 are provided in the nozzle plate 10 so that the conduction paths 101 are communicated with the nozzle opening sections N to correspond to the plurality of head chips 110. |
