Ultrasonic probe

An ultrasonic probe comprising:

• an oscillator accommodating part having an accommodation shaft having an ultrasonic oscillator accommodated therein, and a curved surface part connected to one end portion of the accommodation shaft and having formed thereon a curved surface facing a direction opposite to a direction in which the accommodation shaft is present;
• an elastic body receiving the curved surface of the curved surface part and producing an elastic force pressing the curved surface;
• and
• an elastic body accommodating part accommodating the elastic body and the curved surface part and restraining movement of the curved surface part pressed by the elastic body, wherein
• the curved surface part and the elastic body configure a spherical joint,
• the curved surface part includes
• a tapered part formed in a tapered shape on a portion connected to the one end portion of the accommodation shaft,
• the elastic body accommodating part includes
• a restraining part restraining movement of the curved surface part by receiving the tapered shape of the tapered part, and
• the tapered part is configured to directly abut the restraining part which is integrally formed with the elastic body accommodating part, to restrain movement of the curved surface part within the elastic body accommodating part.
