Abstract

PURPOSE:To reduce the cost and enhance and mass productivity, by forming a transducer and a capacity on a sheet of the piezoelectric plate. CONSTITUTION:Both the input and output transducers 9 and 10 are provided on a side surface of the notch in the delay element main body 8. The ultrasonic wave produced from the transducer 9 reaches the transducer 10 via the prescribed transmission path to obtain the delay time of one horizontal scanning period. The split major and minor electrodes D and d are provided on the piezoelectric plate 12 having the transducer 9 by means of the prescribed evaporation mask, and at the same time the electrode A is provided over the entire main surface of the back side. Thus the input transducer 9 is formed with the electrode D and the area of the electrode A under the electrode D and opposing to the plate 12, and the capacity 11 is formed with the electrode d and the area of the electrode A respectively.
