PROBLEM TO BE SOLVED: To obtain a liquid droplet jetting apparatus capable of sealing a piezoelectric transducer to which a flexible printed circuit substrate or the like is connected into a sealed space. SOLUTION: The liquid droplet jetting apparatus is equipped with a pressure generating room communicated with a nozzle opening for delivering liquid droplets, a vibrating plate constituting a part of the wall of the pressure generating room, a piezoelectric transducer comprising lead titanate zirconate formed on the outside face of the vibrating plate, and the flexible printed circuit substrate connected to the piezoelectric transducer. In the liquid droplet jetting apparatus in which the vibrating plate is vibrated by the piezoelectric transducer to generate a pressure in the pressure generating room, and the liquid droplets are delivered from the nozzle opening by the pressure, the piezoelectric transducer is sealed by a plurality of layers of sealing covers 13, 16 and 17.
