An ultrasound probe includes a laminated body having: a piezoelectric body having a thickness in a first direction； a first electrode and a second electrode that face each other so as to sandwich the piezoelectric body in the first direction； an intermediate layer that is electrically connected with the second electrode and that is provided on an opposite side to the piezoelectric body with respect to the second electrode； and a third electrode that extends in a second direction that is orthogonal to the first direction. A plurality of the first electrodes and second electrodes are arranged at predetermined intervals in the second direction. A plurality of the laminated bodies are arranged in a third direction. A first groove that penetrates through the first electrode, the piezoelectric body, and the second electrode and a part of the intermediate layer is formed in the laminated body.
