<P>PROBLEM TO BE SOLVED: To provide a head chip which can print a desired shape suppressing shift to a medium to be recorded while a resolution for printing to the medium is enhanced, and to provide a liquid jet head and a liquid jet apparatus. Ž<P>SOLUTION: The head chip 26 has a nozzle plate where a plurality of liquid jet holes 45 to eject a liquid W are formed and a plurality of piezoelectric actuators 49a and 49b which have a plurality of grooved parts 48 where the liquid is stored and which press the liquid in the plurality of grooved parts towards the side of the plurality of liquid jet holes. A plurality of channels 54 are prepared between the nozzle plate and the plurality of piezoelectric actuators, which guide the liquid to the plurality of liquid jet holes, respectively. The plurality of liquid jet holes are arranged on one straight line C. The plurality of liquid jet holes and the plurality of grooved parts are made to communicate with each other via the plurality of channels. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
