A liquid droplet jetting apparatus is provided. The liquid droplet jetting apparatus includes: a plurality of pressure chambers, in each of which is disposed a nozzle for jetting a liquid filling the pressure chambers; a common supply channel that is equipped with branching channels connected to each of the pressure chambers and which supplies the liquid to each of the pressure chambers from the branching channels such that the liquid fills each of the pressure chambers; and a pressure applying component that applies pressure to the liquid filling the pressure chambers to cause the liquid to be jetted from the nozzles such that a frequency of pressure waves propagating in the liquid inside the common supply channel when pressure has been applied to the liquid filling the pressure chambers does not become equal to a resonance frequency of the common supply channel.
