Claim 10:
11. A sheet-shaped magnetic marker to be laid on a road surface so as to be able to be detected by a magnetic sensor attached to a vehicle to achieve assist for driving operation of the vehicle by a driver or control on a vehicle side to achieve automatic driving independently from operation of the driver, wherein
the magnetic marker is divided into at least two regions by a continuous or intermittent cut line,
the magnetic marker is configured so that, when each region of said at least two regions is peeled off from the road surface, isolation can be made by the cut circular line from an adjacent region,
said cut lines include a plurality of concentrically-cut lines having a same center and different diameters and a cut line which divides, in a circumferential direction, annular regions obtained by division by the plurality of concentrically-circular cut lines, and
the magnetic marker is configured so that, of said at least two regions configuring the magnetic marker, a region positioned on an outer circumferential side can be isolated by the cut line from an adjacent region on an inner circumferential side, and each region configuring the magnetic marker is peeled off from the outer circumferential side.
