PROBLEM TO BE SOLVED: To solve the problem that defectiveness may occur in maintenance, and there are no regular performance-monitoring means for coping with electromagnetic wave wiretapping, electromagnetic wave interference, or the like in a monitoring system for an electromagnetic shielding chamber used as an office. SOLUTION: This electromagnetic shielding chamber-monitoring system has a transmitting device that generates a radio frequency signal, an antenna for transmission that is installed at one of the inside and outside of the electromagnetic shielding chamber and changes the inputted radio frequency signal to a radio wave for transmitting, an antenna for reception that is installed at the other and receives the radio wave, a receiving device that takes out the signal component of the radio frequency signal as a signal to be monitored from the reception radio wave of the antenna for reception, and a monitoring device that monitors the reception level of the antenna for reception according to the signal to be monitored.
