PROBLEM TO BE SOLVED: To provide a liquid jetting apparatus capable of remarkably reducing noise at the time of controlling micro vibration while maintaining a preferable micro vibration frequency. SOLUTION: This liquid jetting apparatus comprises a head member 8 having 2 or more (n) pieces of nozzle openings 51, and a micro vibration means 35 for generating micro vibration in a liquid at each nozzle opening 51. The micro vibration means 35 is driven so as to have micro vibration in the liquid at all the nozzle opening 51 by a certain cycle T, such that the micro vibration is generated by a timing delayed by T/n per each nozzle opening 51.
