ABSTRACT:
A liquid jetting head of the invention includes a nozzle plate having a plurality of nozzles and a flowing-path plate layered on the nozzle plate. The flowing-path plate has a plurality of nozzle-communicating chambers and a plurality of elongated pressure-chambers. The plurality of nozzle-communicating chambers respectively communicate with the plurality of nozzles, the plurality of pressure-chambers respectively communicate with the plurality of nozzle-communicating chambers, and the plurality of pressure-chambers are open to a side away from the nozzle plate. A vibrating plate commonly seals the open surfaces of the plurality of pressure-chambers of the flowing-path plate, and a plurality of pressure-generating units respectively changes pressures of liquid in the respective pressure-chambers. The plurality of nozzles are aligned on a line segment, and at least one of the pressure-chambers communicating with at least one of the nozzles in the vicinity of an end of the line segment is formed so as to have a shorter length than at least one of the pressure-chambers communicating with at least one of the nozzles away from the end of the line segment.
