Abstract: In order to provide a technology that does not require, in a probe, provision of a bias voltage storage unit and a communication unit and, in an apparatus main body, provision of a communication unit configured to communicate to/from the probe and a unit configured to control a bias voltage based on a value obtained by the communication, there is provided a probe including a plurality of cells, the cell including a first electrode and a second electrode disposed so as to be opposed to the first electrode across a gap. The plurality of cells include: a first cell configured to perform at least one of transmission or reception of an ultrasound wave; and a second cell in which pull-in occurs at a voltage lower than a pull-in voltage of the first cell and which is configured to be short-circuited at a time of the pull-in.
