ABSTRACT:
A liquid droplet discharge unit for discharging liquid droplets from nozzles is disclosed, and this liquid droplet discharge unit is constructed in such a way that plural nozzles are communicated with plural pressure chambers in which liquid is filled, the volumes of the respective pressure chambers are changed by plural drive elements to cause liquid droplets to be discharged from the respective nozzles. Further, one heat pipe, which is in thermal communication with the drive elements and moves heat to one end in the axial direction, is provided. A liquid droplet discharge apparatus equipped with such a liquid droplet discharge unit is also disclosed.
