To provide an ultrasonic diagnosis device which can be simply manufactured and can detect an ultrasonic wave with excellent sensitivity and accuracy. An ultrasonic diagnosis device in which a transmitting piezoelectric element and a receiving piezoelectric element are supported on a substrate supported parallel to a radial artery by support means such that their widths a, c are respectively 0.38-1.1 mm and a gap b between them is 0.05-4.0 mm, an ultrasonic wave is transmitted from the transmitting piezoelectric element, a reflected wave from the radial artery is received by the receiving piezoelectric element, and a pulse wave is detected on the basis of a detection result of the reflected wave.
