PROBLEM TO BE SOLVED: To provide an action level indicator configured to directly measure the electric current flowing from a living body.
SOLUTION: The level indicator has a recess, a mono-polar connector and a display part on the surface of a casing. A plate-shaped contact electrode approximately matching the shape of the recess is attached to the recess in the casing so that an operated person can touch the electrode. The connector is configured to be connected to the output on the grounding side of a potential generating device via a cable. A rectification circuit is disposed within the casing to be connected to the contact electrode and the connector. The level indicator also comprises a smoothing circuit for smoothing rectification signals rectified by the rectification circuit, an amplification circuit for amplifying the smooth signals smoothed by the smoothing circuit, the display part for displaying the level of the signals amplified by the amplification circuit and a battery for feeding the electric power to the respective circuits, which are housed in the indicator. The level of signals flowing from the potential generating device to an electric floor, to the operated person, to the level indicator and to the potential generating device is measured and displayed by using the level indicator.
