Abstract: PURPOSE:To enable detection of a longitudinal wave of ultrasonic waves by using an ultrasonic wave receiving element in which columnar ceramic piezoelectric bodies are arrayed in a synthetic resin matrix. CONSTITUTION:Vibration of an ultrasonic wave reaching the surface 7 of an object to be inspected from within the object is transmitted to a wave receiving plate 1 to compress a columnar ceramic piezoelectric body 21 of a synthetic resin-ceramic compound piezoelectric element 2 along the length thereof through an electrode 23. Then, with the compression of the ceramic piezoelectric body, a potential difference is caused between both ends of the columnar piezoelectric body 21 and measured at a pair of lug terminals 6 and 6 through a pair of electrodes 23 and 24 and a pair of leads 5 and 5. In this manner, an ultrasonic wave reaching the surface 7 of the object to be inspected is detected or an intensity of the ultrasonic wave can be measured. As the ultrasonic wave as longitudinal wave alone is detected on the surface 7 of the object to be inspected to measure the intensity thereof, the intensity of and a change in the ultrasonic wave can be measured faithfully as generated at a wave source within the object to be inspected.
