PROBLEM TO BE SOLVED: To provide a driving signal generation circuit which permits a loss in power consumption to be reduced. SOLUTION: The driving signal generation circuit has a current amplification circuit receiving the input of an original driving signal and outputting a driving signal to charge and discharge a capacitive load in accordance with a voltage change of the original driving signal and a regenerative circuit regenerating electrical current from a terminal to the power of a second voltage by making the voltage of the terminal to which charges are released from the current amplification circuit at the time of the discharging of the capacitive load a first voltage and reducing the first voltage to the second voltage.
