According to the present embodiment, the ultrasound probe (3) includes a piezoelectric vibrator (354), an open/short switching board (321), a short terminal (322), and a GND terminal (38). Then, the open/short switching board (321) and the short terminal (322) switch between a short state in which the electrode of the piezoelectric vibrator (354) is connected to the GND terminal (38) and an open state in which the electrode of the piezoelectric vibrator (354) is not connected to the GND terminal (38), at any timing. |
