Abstract
An ultrasonic probe () comprises a cMUT chip (), which has a plurality of vibration elements whose electromechanical coupling coefficient or the sensitivity changes depending on a bias voltage, and transmits/receives an ultrasonic wave; an acoustic lens () provided on the ultrasonic wave radiation side of the cMUT chip (); a backing layer () provided on the back side of the cMUT chip () for absorbing propagation of the ultrasonic wave; an electric wiring portion (flexible substrate ()), which is provided from the peripheral portion of the cMUT chip () to the side face of the backing layer () and has a signal pattern connected with the electrode of the cMUT chip () arranged thereon; and a housing (ultrasonic probe cover ()) for containing the cMUT chip (), the acoustic lens (), the backing layer () and the electric wiring portion (flexible substrate ()). A ground layer (conductive film ()) of ground potential is provided on the ultrasonic wave radiation side of the cMUT chip ().
