Patent ID: 8454518

Claim:
An ultrasonic probe having a backing load member and a plurality of piezoelectric elements arranged to be spaced apart from each other on an upper surface of the backing load member, the ultrasonic probe comprising: a first polymer film provided between the backing load member and the plurality of piezoelectric elements and provided with electric terminals individually arranged so as to correspond to the respective piezoelectric elements; a first acoustic matching layer provided on an upper surface of the plurality of piezoelectric elements and individually arranged so as to correspond to the respective piezoelectric elements; a second polymer film provided on an upper surface of the first acoustic matching layer and provided with electric terminals individually arranged so as to correspond to the respective piezoelectric elements, wherein the second polymer film is divided so as to correspond to the respective piezoelectric elements; a second acoustic matching layer provided on an upper surface of the second polymer film and individually arranged so as to correspond to the respective piezoelectric elements; and a third acoustic matching layer provided as a continuous, undivided layer extending over an upper surface of the second acoustic matching layer corresponding to the respective piezoelectric elements and formed of a rubber elastic material.
