波遅延媒体。[Claims for Utility Model Registration] (1) An ultrasonic delay medium in which an electromechanical transducer is attached to one end face, and the width of the piezoelectric body of the electromechanical transducer is the width of the main signal path. On the main surface of the ultrasonic delay medium, reference is made to a rectangular area surrounded on all sides by the main signal path, a rectangular area surrounded on all sides by the main signal path and the end face of the ultrasonic delay medium, or a triangular area surrounded on three sides. This includes both inside and outside the area, but inside the ultrasonic delay medium, it enters a part other than the main signal path or a part of the periphery of the main signal path. 1. An ultrasonic delay medium characterized in that a conical recess with a straight body is provided. (2) The ultrasonic delay medium according to claim 1, wherein a sound absorbing material is applied to a conical concave portion provided with a straight body portion.
