A capacitive load driving device includes a drive waveform generator adapted to generate a drive waveform signal, a subtraction section adapted to output a differential signal between the drive waveform signal and two feedback signals, a modulator adapted to perform pulse modulation on the differential signal to obtain a modulated signal; a digital power amplifier adapted to power-amplify the modulated signal to obtain an amplified digital signal, a low pass filter including an inductor and a capacitor, and adapted to smooth the amplified digital signal to obtain a drive signal of a capacitive load, a first feedback circuit adapted to feedback the drive signal to the subtraction section as a first feedback signal, and a second feedback circuit adapted to set forward a phase of the drive signal and to feed back the drive signal to the subtraction section as a second feedback signal.
