<p>PROBLEM TO BE SOLVED: To provide an ultrasound device which can sufficiently suppress the shear deformation of an acoustic lens with respect to shear force.SOLUTION: A substrate 21 comprises an element array comprising a plurality of thin film type ultrasonic transducer elements 23 disposed on a base material 44 in the form of array. The element array is covered with an acoustic matching layer 51. On the acoustic matching layer 51 an acoustic lens 52 is disposed. To the substrate 21, a structure 53 in contact with the acoustic lens 52 is fixed. The structure 53 has a larger modulus of rigidity than that of the acoustic lens 52.</p> |
