Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an ink-jet head capable of absorbing variation of an ink feeding pressure by an air chamber, maintaining discharge stability, and effectively preventing flow-out or loss of air from the air chamber. SOLUTION: The ink-jet head includes an ink-jet head chip having a nozzle array, a manifold which leads the ink to the ink-jet head chip, and a first ink channel which leads the ink from outside to the manifold. The ink-jet head includes, the air chamber and a second ink channel which branches from the middle of the first ink channel and is connected to the air chamber. At least part of the member which is in contact with the air confined in the air chamber and forms the air chamber has air permeability. COPYRIGHT: (C)2008,JPO&INPIT
