In a marker detection method in which a sensor unit(11) that includes a plurality of magnetic sensors arranged in a vehicle width direction is used to detect magnetic markers(10) laid in a road, a feature value that represent symmetry of magnetic distribution, which is the distribution of magnetic measurement values obtained by each magnetic sensor included in the sensor unit (11) is generated, and threshold process regarding the feature value is executed to determine the possibility of the presence of magnetic generation source other than magnetic marker (10) , that causes disturbance, and hence to suppress erroneous detection.
