Abstract
An ultrasound probe includes: a metal case including a bottom wall portion having a vibration surface, and a side wall portion connected to the bottom wall portion; a coil mounted on one surface of the side wall portion; and a magnet mounted in such a way as to sandwich the coil between the magnet and the one surface of the side wall portion, in which the coil causes an eddy current to occur in the one surface of the side wall portion, and causes the bottom wall portion to vibrate, by using a Lorentz force occurring in the side wall portion because of the interaction between the eddy current and a magnetic field generated by the magnet.
