Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an inkjet head that can prevent a nozzle of the inkjet head from being damaged so as to cause a discharge defect, due to contact between the nozzle and a recording medium.SOLUTION: A nozzle guard 22 with a nozzle hole exposed is arranged on a nozzle surface 34 so as to prevent a nozzle from contacting a recording medium. Further a plate 32 is inserted between the nozzle guard and the nozzle surface so as to prevent ink from entering between the nozzle guard and the nozzle surface and reduce amounts of ink overflowing.SELECTED DRAWING: Figure 3 【課題】インクジェットヘッドのノズルと記録媒体が接触することにより、ノズルが損傷し、吐出不良の原因となることを防止することができるインクジェットヘッドを提供する。【解決手段】ノズル面３４にノズル孔を露出させたノズルガード２２を配置することで、ノズルと記録媒体の接触を防止した。さらに、ノズルガードとノズル面の間にプレート３２を挿入し、ノズルガードとノズル面の間にインクが入り込みにくくし、また、はみ出すインクの量を少なくした。【選択図】図３
