Provided is a capacitive transducer drive device capable of adjusting a potential difference applied between electrodes of a cell with a simple configuration. A capacitive transducer to be driven by the drive device includes a cell including: a first electrode included in a vibrating membrane; and a second electrode formed to oppose the first electrode through intermediation of a gap. One of the first electrode and the second electrode of the cell is electrically connected to a first DC voltage applying unit, and the other of the first electrode and the second electrode of the cell is electrically connected to a second DC voltage applying unit. A voltage to be applied by the second DC voltage applying unit is set to be lower than a voltage to be applied by the first DC voltage applying unit. The voltage to be applied by the second DC voltage applying unit is variable.
