Abstract:
A liquid jet head includes: a pressure generation element; a nozzle plate which is provided with a nozzle opening; a pressure generating chamber plate in which a pressure generating chamber for communicating to the nozzle opening is formed; and a nozzle communication plate in which a communication through hole for communicating the one pressure generating chamber with a plurality of nozzle openings is provided between the nozzle plate and the pressure generating chamber plate, so that, for example, a plurality of the nozzle openings can be disposed in a lined-up direction of the pressure generating chambers at a predetermined pitch smaller than a lined-up pitch of the pressure generating chamber.
