Abstract
A capacitive load driving circuit that drives a capacitive load, includes: a power supply unit that generates different voltages; a plurality of charge storage elements that are charged with the different voltages generated by the power supply unit; and a load driving section that connects a charge storage element arbitrarily selected from the plurality of charge storage elements to the capacitive load to drive the capacitive load, and connects, when at least two of the charge storage elements are selected, the at least two charge storage elements to the capacitive load in a state where the at least two charge storage elements are connected in series.
