Abstract
An ultrasonic probe has a case of a substantially cylinder shape having a first axis along longitudinal direction thereof. The case has a convex wall in the vicinity of a closed end of the case. The convex wall is transparent to an ultrasonic signal radiated from the ultrasonic probe. A support cylinder having a second axis is rotatably mounted in the case. The support cylinder and the convex wall are coaxial to the second axis. An ultrasonic transducer is fixed on a base of the support cylinder. A viscous resin fills a space between the convex wall and the ultrasonic transducer. Thus, a convex lens coaxial to the second axis is formed by the convex wall and the viscous resin. The angle of the axis of the convex wall to the first axis may be chosen between zero degree to approximately 90 degrees.
