ABSTRACT:
A plurality of pressure chambers are divided into a first pressure chamber group and a second pressure chamber group, and are arranged such that an interval of the first pressure chamber group and the second pressure chamber group is larger than an interval between nozzles, and sub ink supply passage which supplies the ink to the common liquid chambers through the space is formed. Accordingly, a liquid droplet jetting head which is capable of delivering the ink to all the nozzles without increasing a size is provided.
