PROBLEM TO BE SOLVED: To provide a mechanism for transmitting ultrasonic receiving signals between a rotating part and a non-rotating part of an ultrasonic probe, capable of preventing wear caused by sliding as much as possible while bringing the rotating part and the non-rotating part into contact with each other. SOLUTION: The ultrasonic receiving signals are transmitted between the rotating part and non-rotating part by bringing a contact point for taking out signals connected to the non-rotating side into contact with the center of an electrode for taking out signals mounted on an end surface of a rotation shaft as the contact between the rotating part and the non-rotating part in a low sliding part, or by bringing the rotating part and the non-rotating part into contact with each other via a ball bearing used as a bearing of the rotation shaft.
