1. A backing element of an ultrasonic probe, the backing element comprising:
- a member which is a component of a backing layer having a shape of a polygonal column that is configured to acoustically connect to an ultrasonic transducer element;
a conductive trace disposed at a first surface of the member and electrically connected to the ultrasonic transducer element; and
an electrode layer disposed on a second surface of the member, different from the first surface on which the conductive trace is disposed,wherein the second surface of the member is acoustically connected to the ultrasonic transducer element,the member has a recessed portion on the second surface, the electrode layer being divided by the recessed portion, andportions of the electrode layer divided by the recessed portion are electrically connected through the ultrasonic transducer element.

Abstract
A backing element of a ultrasonic probe, a backing layer of a ultrasonic probe, and a manufacturing method thereof, the backing layer formed by arranging a plurality of members each having a shape of a polygonal column in a one-dimensional manner or in a two-dimensional manner while each of the plurality of members is provided with a conductive trace formed at one side surface thereof, thereby electrically connecting an ultrasonic transducer array, which is being acoustically connected to the backing layer, in a further simple and definite manner.
