The droplet discharge head (12, 50) comprises: a nozzle (71) which discharges droplets of a liquid; a pressure chamber (70) which is in communication with the nozzle (71) and is filled with the liquid to be discharged from the nozzle (71); and a pressure generation device (92) which generates pressure variation in the liquid inside the pressure chamber (70) and causes the droplets to be discharged from the nozzle (71), wherein: the pressure chamber (70) has a substantially triangular planar shape; the pressure chamber (70) is provided with a first conduit (81) which conducts the liquid from the pressure chamber (70) to the nozzle (71), a second conduit (85) which causes the liquid to flow into the pressure chamber (70), a third conduit (86) which drains the liquid in the pressure chamber (70) to exterior of the pressure chamber (70), and a switching device (94) which opens and closes a flow channel in at least one of the second and third conduits (85, 86); and the first, second and third conduits (81, 85, 86) are connected to the pressure chamber (70) at positions in vicinity of different vertices of the substantially triangular shape, respectively. <IMAGE> |
