Abstract

PURPOSE:To obtain an ultrasonic probe provided with sharp directivity by curving the ultrasonic radiation surfaces of piezoelectric elements to a hollow surface shape in section. CONSTITUTION:High polymer piezoelectric elements 7a, 7b, 7c- of polyvinylidene fluoride or the like are affixed by means of adhesive 8 onto a packing material 6 of rubber, plastics or the like. The ultrasonic sound radiation surfaces 9 of these elements 7 are curved to a hollow surface shape in the section along the arranging direction of the elements 7; hence, the elements 7 are formed in a so-called trough shape. Then, ultrasonic beams 10 radiated by the respective elements 7 are focused with respect to the arranging direction of the elements 7, and exhibit sharp directivity. The hollow surface shapes of the surfaces 9 may be constituted to an arc surface, parabolic surface, etc.
