摘要： Disclosed is an ultrasonic probe comprising: CMUT cells (13) that mutually convert ultrasonic waves and electrical signals; a semiconductor substrate (15) that has a plurality of the CMUT cells (13) formed on the surface thereof; an acoustic lens (3) that is provided on the front face side of the CMUT cells (13); and a backing layer (5) that is provided on the rear face side of the semiconductor substrate (15). The backing layer (5) is formed by a first backing layer (27) that makes contact with the semiconductor substrate, and a second backing layer (29) that is provided on the rear face side of the backing layer (27). The acoustic impedance of the backing layer (27) is set based on the sheet thickness of the semiconductor substrate (15). The backing layer (29) is formed by attenuating material capable of attenuating ultrasonic waves transmitted through the backing layer (27). Multiple reflection of reflection echoes is suppressed by setting the acoustic impedance of the backing layer (29) to match the acoustic impedance of the backing layer (27).

摘要： Disclosed is an ultrasonic probe wherein the warpage of a CMUT due to thermal stress produced at the joint between a backing layer and the CMUT is minimized, thereby improving the durability of the bond between the CMUT and the backing layer. To accomplish this the ultrasonic probe is provided with: a CMUT (20) having vibratory elements that change the electromechanical coupling coefficient or sensitivity according to the bias voltage to be applied; a backing layer (22) adhered to the rear side of the ultrasonic transmission surface of the CMUT (20); and a thermal-stress balancing member (24) to be adhered to the backing layer (22) while being disposed facing the CMUT (20) in such a manner that the backing layer (22) is sandwiched therebetween so as to minimize the warpage of the CMUT (20) due to thermal stress produced between the CMUT (20).
