Abstract
An ultrasonic diagnostic probe includes: a swinging mechanism for swinging a piezoelectric vibrator provided in an accommodating part at an end of a tube-like shaft, around an axis parallel with an ultrasonic transmission and reception face; and a rotating mechanism for rotating the piezoelectric vibrator around an axis perpendicular to the ultrasonic transmission and reception face. The rotating mechanism includes: a pedestal provided with a semicylindrical part; a seat pedestal in which a concave part having a curvature that matches the semicylindrical part is formed so as to rotatably support the pedestal by the semicylindrical part being engaged with the concave part; and a swinging wire for urging the pedestal into a swinging motion.
