PROBLEM TO BE SOLVED: To eliminate a problem of difficulty in detecting a tissue in a necessary part in a human body 4 due to impossibility of vertical radiation of ultrasonic waves to the human body 4 from an ultrasonic vibrator installed inside a probe main body 1 because of hardness of vertically supporting a grasping part 3 to the human body 4 as a contact surface of a water bag 2 with the human body 4 is flexible when the water bag 2 is brought to get in contact with the human body 4 by holding the grasping part 3. SOLUTION: Plural ultrasonic vibrators are installed in the probe main body 1, the water bag 2 is installed on an ultrasonic radiation part 1a in the probe main body 1, and the grasping part 3 is installed on a facing part in the probe main body 1 to the water bag 2. A reflection plate 5 inclined for about 45 deg. is installed on an ultrasonic radiation surface 1a in the probe main body 1 from one wide end 1b to the other wide end 1c.
