PROBLEM TO BE SOLVED: To provide a liquid droplet jet head which can prevent enlargement due to an increase of the number of nozzles. SOLUTION: The liquid droplet jet head is equipped with a nozzle plate 6 which has a plurality of nozzles 6b arranged in one array and a plurality of liquid channels 6a that respectively communicate with the plurality of nozzles 6b and extend in the same direction, a liquid chamber plate which has above the plurality of liquid channels 6a a plurality of liquid chambers 5a that respectively communicate with the plurality of liquid channels 6a, and a plurality of piezoelectric elements 3a set with respective one ends opposed to the plurality of liquid chambers 5a. A distance between a predetermined nozzle 6b and other nozzles 6b at the liquid chambers 5a each communicating with the adjacent other nozzles 6b changes periodically. COPYRIGHT: (C)2009,JPO&INPIT
