Ultrasound transducer

An ultrasound transducer comprising:

• a piezoelectric element, the piezoelectric element includes a flat piezoelectric body, a first electrode that is laminated on at least one side of the piezoelectric body in a thickness direction, and a second electrode that is laminated on at least the other side of the piezoelectric body in the thickness direction;
• a support member, the support member includes a first terminal that is connected to the first electrode of the piezoelectric element, and a second terminal that is connected to the second electrode of the piezoelectric element;
• and
• the first terminal and the second terminal respectively include portions that do not overlap the piezoelectric element in the thickness direction,
• wherein the support member includes a support main body portion that is laminated on the piezoelectric element at the other side in the thickness direction, and extends externally further than the piezoelectric element in a direction orthogonal to the thickness direction;
• the first terminal and the second terminal are supported by the support main body portion, and wherein the support member is configured as a sound absorbing member;
• electrical signal lines connected to the first electrode and the second electrode;
• and
• wherein the support member includes a support main body, the support main body having a pair of grooves that receive the electrical signal lines connected to the first electrode and the second electrode, the pair of grooves being sectioned on a top surface of the support main body portion opposed to a surface of the piezoelectric element;
• and an acoustic matching member, the acoustic matching member arranged on one side of the piezoelectric element, and the support member arranged on an opposite side of the piezoelectric element.
