PROBLEM TO BE SOLVED: To provide a monitoring device of human body potential and a human body potential monitoring method, capable of discharging the charge accumulated on a human body, measuring the surface potential of the human body, and issuing a warning, when a ground line for discharging the charge of the human body is cut or a connection failure thereof occurs. SOLUTION: This monitoring device of human body potential has a ground plate 11, arranged on a wrist strap 10 for discharging the charge accumulated on the human body through the ground line; a monitor plate 12 arranged on the wrist strap 10; a human body potential measuring circuit part 20 for measuring the human body potential with an electrostatic field sensor connected to the monitor plate 12; and an alarm generating circuit 31 for comparing an output signal from the human body potential measuring circuit part 20 with a prescribed reference value, detecting the loss in the conduction path to the ground line of the ground plate 11, and issuing an alarm.
