PROBLEM TO BE SOLVED: To provide an inkjet head having a structure enabling packaging with an effective arrangement relationship of an ink chamber and a nozzle by solving the problems in the related art that a group of oscillators is necessary for each nozzle row in order to increase a packaging density by disposing a plurality of nozzle rows arranged in a row in a plate shape, and that in case of a line type recording device of a fixed head type, the device construction is limited only to packaging of arranging each head alternately. SOLUTION: The inkjet head is characterized in that chamber plates each having a pressure generating chamber having a width wider than those of the first and second grooves are laminated on an ink flow passage substrate on the right and reverse surfaces of which groove rows composed of a group of the first groove communicating with a common ink storage part and the second groove communicating with a nozzle opening part are formed alternately.
