PROBLEM TO BE SOLVED: To provide a liquid jet device reducing loss while securing the waveform accuracy of a driving signal. SOLUTION: In the liquid jet device, a plurality of nozzles for jetting liquid are formed on a liquid jet head 2 and also nozzle actuators 22 are disposed for the respective nozzles thereon, and the liquid is jetted toward a printing medium 1 from the corresponding nozzle by driving the respective nozzle actuators 22 according to the driving signal COM. The liquid jet device is equipped with a digital driving circuit 23 outputting a digital driving signal COMd by power-amplifying a driving waveform signal for digital driving WCOMd when driving the nozzle actuator 22, and an analog driving circuit 24 outputting an analog driving signal COMa by power-amplifying a driving waveform signal for analog driving WCOMa when driving the nozzle actuator 22. Driving pulses PCOM1 and PCOM 3 for which high waveform accuracy is not required are output from the digital driving circuit 23, and a driving pulse PCOM2 for which high waveform accuracy is required is output only from the analog driving circuit 24.
