1. An ultrasonic imaging device comprising:

  • a cell array with a plurality of cells each including a first electrode, a first member covering the first electrode, a second electrode installed opposite the first electrode, a second member covering the second electrode, and a wall member connecting the first member and the second member together; and

    a voltage controller configured to control a voltage applied to between the first electrode and the second electrode,wherein the voltage controller includes a direct voltage application section configured to apply a direct voltage to between the first electrode and the second electrode, an alternating voltage application section configured to apply an alternating voltage to between the first electrode and the second electrode, and a waveform controller configured to temporally vary an amplitude ratio of the alternating voltage based on voltage values of the alternating voltage and the direct voltage.
