PROBLEM TO BE SOLVED: To provide a liquid discharge device which can stabilize the discharge of droplets by enhancing the waveform accuracy of a drive signal for driving a piezoelectric element to discharge the droplets, even if the drive signal has a high frequency.SOLUTION: A drive circuit including transistors M3 and M4 and a low-pass filter D-class amplifies and generates a drive signal for driving a piezoelectric element. The low-pass filter is individualized by an inductor L2 and a capacitor C10. A leadless type is used as the capacitor C10. |
