An ultrasonic probe (100) includes an oscillator accommodating part (110), a first coil spring (130), and a collar (140). The oscillator accommodating part (110) has an accommodation shaft (116) having an ultrasonic oscillator (111a) accommodated therein, and a curved surface part (114) connected to one end portion of the accommodation shaft (116) and having formed thereon a curved surface (114a) facing a direction opposite to a direction in which the accommodation shaft (116) is present. The first coil spring (130) receives the curved surface (114a) of the curved surface part (114), and produces an elastic force pressing the curved surface (114a). The collar (140) accommodates the first coil spring (130) and the curved surface part (114), and restrains movement of the curved surface part (114) pressed by the first coil spring (130). The curved surface part (114) and the first coil spring (130) configure a spherical joint (100J).
