ULTRASONIC PROBE AND ULTRASONIC DIAGNOSIS DEVICE

摘要

An ultrasonic probe and an ultrasonic diagnosis device which can enhance electrical safety for the operator. The ultrasonic probe has an insulating portion (62) between a mounting board (43) and the housing portion (25). Since leak from the internal device of the ultrasonic probe (2) can be prevented, electrical safety of the ultrasonic probe (2) can be enhanced for the operator. A conductive film (61) is provided on the ultrasonic wave radiation side of a cMUT chip (20), and a conductive member (63) is provided along the insulating member (62). The conductive film (61) and the conductive member (63) are connected by a conductive member (64). A closed space of ground potential is formed by the conductive film (61), the conductive member (63) and a coaxial cable (55) connected with the ground. Main constitutive elements of the ultrasonic probe (2) and the body circuit are contained in the closed space of ground potential and shielded electrically from the outside.
