Abstract
An ultrasound probe includes: a transducer array in which a plurality of transducers configured to transmit and receive ultrasonic waves are arrayed with longitudinal directions of the transducers aligned; and a pair of housings each having a plate shape, the housings being configured to sandwich the transducers, the housings including a first conductive portion provided on a first face positioned on a side of each of the transducers, an insulating portion provided on an outer edge portion of a second face that is positioned on an opposite side of the first face, a second conductive portion provided on the second face, and a third conductive portion electrically connecting the first conductive portion and the second conductive portion.

An ultrasound probe comprising:
- a plurality of transducers arrayed with a longitudinal direction, each of the plurality of transducers extending in a direction intersecting the longitudinal direction;
- a first plate including
- an outer surface,
- a first inner surface,
- a first material that is electrically conductive and is located on the first inner surface,
- a through hole, the through hole penetrating the first plate in the direction intersecting the longitudinal direction, and
- a second material that is electrically conductive and is located on the outer surface and around an opening of the through hole;
- and
- a second plate facing the first plate,
- wherein the plurality of transducers are located between the first plate and the second plate to extend in the direction intersecting the longitudinal direction,
- wherein the through hole having a second inner surface, the first plate further includes a third material being electrically conductive, the third material located on the second inner surface,
- wherein the second material is electrically connected to the first material via the third material.
