Abstract
An ultrasonic probe includes a housing, a piezoelectric element provided in the housing, the piezoelectric element emitting an ultrasonic beam, and a refracting member rotatably provided in the housing. The refracting member has a first surface opposite to the piezoelectric element and a second surface at which the ultrasonic beam emitted from the piezoelectric element and passing through the first surface is deflected in a state where a deflection angle between an axis perpendicular to a surface of the piezoelectric element and a deflected ultrasonic beam changes as the refracting member rotates.
