PROBLEM TO BE SOLVED: To provide an acoustic wave probe that eliminates the need for the movement of an acoustic wave sensor and the reattachment of an acoustic wave sensor as much as possible even when the shape or the size of a subject has changed.SOLUTION: An acoustic wave probe 1 includes an acoustic wave transducer, a contact member 3 that contacts a subject to be measured, and a support member 2 for supporting the acoustic wave transducer and the contact member. The contact member 3 can hold a medium that propagates an acoustic wave between the subject and the acoustic wave transducer inside, and can change a degree of contact between the subject and the contact member by supplying the medium inside the contact member to expand the contact member, or by discharging the medium from inside the contact member to contract the contact member.SELECTED DRAWING: Figure 1 |
