The present invention addresses the problem of achieving a reduction in power consumption through regeneration of electric power by transferring electric charge in a capacitive load, to which a high voltage was being applied immediately before, to another capacitive load. This capacitive load drive circuit is connected to multiple terminals (VOUTP, VOUTM) having multiple capacitive loads respectively connected thereto and causes the voltage of one of the multiple terminals to change from a low state to a high state, said capacitive load drive circuit being provided with: a current change detection circuit (Q p 11-Q p 13, Q n 11-Q n 13; Q p 21-Qp23, Q n 21-Q n 23) for detecting a change in current at each output stage (11A, 11B) of an amplifier; a reference current generation circuit (Q p 1, Q p 14, Q n 1, Q n 14; Q p 2, Q p 24, Q n 2, Q n 24; Q p 31, Q p 32) for generating a reference current proportional to an output current from the output stage of the amplifier; and an electric charge transfer circuit (Q n 40-Q n 42) that applies a current proportional to the reference current to one of the multiple terminals according to the detection result of the current change detection circuit so as to cause the electric charge to be transferred from the capacitive load connected to the terminal in the high-voltage state to the capacitive load connected to the terminal in the low-voltage state.
