Abstract
There is disclosed a small and thin ink jet head having an excellent productivity, in which Piezoelectric elements capable of developing a large displacement amount and a high displacement generation force can highly densely be arranged together with ink chambers and nozzles and in which generation of crosstalk is inhibited. A discharge device comprises a channel section in which a plurality of channels are formed, each channel having an introduction hole, a pressurizing chamber and a discharge hole; and an actuator section having a top plate, a pair of support walls arranged at opposite ends of the top plate and a plurality of piezoelectric elements hanging from the top plate, spread between the pair of support walls, arranged independently of one another and forming pairs with the channels.
