ABSTRACT:
Ink is reserved in a cartridge case. On this cartridge case, there are fixed an ink jet head and an electric connecting member in a stacked state. The ink jet head is constructed to include: ink supply holes adapted to be supplied with the ink from the cartridge case; ink passages communicating with the ink supply holes; nozzles formed in the leading ends of the ink passages; and ink ejecting device such as piezoelectric elements disposed to correspond to the ink passages for ejecting the ink from the nozzles. These nozzles and the ink passages are substantially perpendicular. Moreover, the stacking direction, the ink supply direction from the cartridge case to the ink supply holes, and the ink ejecting direction from the nozzles are made substantially identical. The electric connecting member is made of a flexible frame or a metal lead frame. Thus, the ink jet head is assembled merely by stacking those individual components in the common direction.
