An ultrasonic probe is provided capable of eliminating difficulties in processing, increasing the directivity of ultrasonic waves, and obtaining a high-resolution diagnostic image. An ultrasonic probe 10 is configured to include a plurality of piezoelectric elements 1, an acoustic matching layer 2 provided on a front surface in the thickness direction at a subject side (upper side in the drawing) so as to correspond to the respective piezoelectric elements 1, a backing load member 3 provided, as necessary, on a rear surface (lower surface in the drawing) in the thickness direction of the piezoelectric elements 1 at a side opposite to the acoustic matching layer 2, and an acoustic lens 4 provided, as necessary, on the acoustic matching layer 2. The acoustic matching layer 2 is formed of a rubber elastic material and arranged in a non-divided, flat surface shape at one side of the plurality of piezoelectric elements 1. |
