A proximity sensor system includes: a plurality of proximity sensors 4 to 7; and a fault diagnostic device 8 that diagnoses the presence or absence of faults in the proximity sensors 4 to 7. Each of the proximity sensors 4 to 7 includes: an electrode 40 to 70; a power circuit 45 that applies voltage at an oscillation frequency to the electrodes; and a measuring circuit 46 that measures electrical characteristics of the electrodes. The fault diagnostic device 8 sets at least two of the proximity sensors as an oscillating target and a diagnostic target, acquires a result of measuring the electrical characteristics with the measuring circuit of the diagnostic target, while the power circuit of the oscillating target is generating electromagnetic waves at the oscillation frequency. The fault diagnostic device 8 diagnoses the presence or absence of faults in the diagnostic target, based on the result of measurement.
