Claim 12:
13. A liquid ejection device, comprising:
a liquid feed pipe connectable to a storage tank; and
a liquid ejection head connected to the liquid feed pipe, the liquid ejection head including:
a base plate with a pair of actuators on an upper surface side of the base plate;
a plurality of pressure chambers formed in each actuator;
a first common chamber connected to a first side of the plurality of pressure chambers, the first common chamber being between the pair of actuators on the upper surface side of the base plate;
a second common chamber connected to a second side of the plurality of pressure chambers in one of the actuators, the pressure chambers in the one of the actuators connecting the first common chamber to the second common chamber;
a nozzle plate on an upper surface side of the pair of actuators and having a plurality of nozzles at positions respectively corresponding to the pressure chambers;
a supply hole in the base plate connected to the first common chamber;
a discharge hole in the base plate connected to the second common chamber; and
a manifold on a lower surface side of the base plate, the manifold having:
a liquid supply flow path for supplying liquid to the supply hole from a liquid feed port on a lower surface side of the manifold, the liquid feed port connected to the liquid supply pipe,
a liquid discharge flow path for receiving liquid from the discharge hole, and
a temperature control flow path through which a temperature control liquid can flow.
