ULTRASONIC PROBE AND METHOD OF MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2023085643
Kind Code:
A
Abstract:
To provide an ultrasonic probe that is improved in directivity and has chemical resistance, and a method of manufacturing the same.SOLUTION: An ultrasonic probe 10 comprises: a vibrator array 40a constituted by arraying many individual vibration parts 110, each consisting of a lamination part comprising a piezoelectric ceramic 40, a first acoustic matching layer 50 and a second acoustic matching layer 60 in this order, in a first direction with predetermined gaps 90; and a resin film 80 which is provided on the second acoustic matching layers as a protective film for the vibrator array. The second acoustic matching layers and the resin film are bonded together with a sheet-type adhesion layer 70. The sheet type adhesion layer is formed of a photocuring adhesive film, and the resin film is formed of polyphenylene sulfide.SELECTED DRAWING: Figure 1
