ABSTRACT:
In an ultrasonic probe produced by forming stripe electrodes on a piezoelectric composite material consisting of a plurality of piezoelectric ceramic rods buried in an organic material, the gaps between the stripe electrodes in the direction of disposition are expanded as much as possible while the gaps of the piezoelectric ceramic rods or their width in the direction of disposition is reduced as much as possible. When the width of the piezoelectric ceramic rod is reduced in the manner described above, the width of the piezoelectric ceramic rod is expanded in a direction orthogonal to the direction of disposition or the gaps of the piezoelectric ceramic rods in that direction is reduced in order to reduce crosstalk and to improve flexibility and sensitivity.
