Patent ID: 8888248

Claim:
A liquid droplet jetting apparatus which jets droplets of a liquid onto an object, comprising: a liquid droplet jetting head including; a liquid droplet jetting surface arranged on a liquid droplet jetting surface plane, formed with a plurality of nozzles from which the droplets are jetted; an energy applying mechanism configured to apply a jetting energy to the liquid in each of the nozzles; and a driving device configured to drive the energy applying mechanism; a relative movement mechanism configured to move, along the liquid droplet jetting surface, the liquid droplet jetting head relative to the object to which the droplets are jetted from the nozzles; and a heat radiating member configured to be provided in the liquid droplet letting head to radiate heat generated m the driving device; wherein the heat radiating member includes a heat radiating surface which is positioned on the liquid droplet jetting surface plane or which is positioned at a downstream side in a jetting direction in which the droplets jetted from the nozzles fly as compared with the liquid droplet jetting surface plane.
