An ultrasonic probe and an ultrasonic diagnosis device which can improve electrical safety for an operator are provided. The ultrasonic probe 2 has an insulating portion 62 between a mounting board 43 and a case 25. Since electrical leakage from the internal device of the ultrasonic probe 2 can be prevented, electrical safety of the ultrasonic probe 2 for the operator can be improved. 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. A conductive film 61 and a conductive member 63 are connected by a conductive member 64. A closed space having a ground potential is formed by the conductive film 61, the conductive member 63 and a coaxial cable 55 connected to ground. Main components or the body circuits of the ultrasonic probe 2 are contained in the closed space having the ground potential and shielded electrically from the outside.
