PROBLEM TO BE SOLVED: To provide a capacitive-type actuator drive circuit and an inkjet head which drive an actuator so that a printing quality may become better with a high reliability and high speed while consuming a sufficiently small energy and freely adjusting the drive waveform. SOLUTION: The electrostatic drive capacitive-type actuator drive circuit 100 possessing an inductor L for storing a current energy from a power source and a capacitive-type actuator CL charged with the current stored in the inductor L makes the capacitive-type actuator CL discharge after holding the voltage charged in the capacitive-type actuator CL for a predetermined time.
