Claim 19:
20. 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 line from an adjacent region,
the magnetic marker before laid on the road surface is retained in a sheet-shaped liner for retaining the magnetic marker, and the magnetic marker can be transferred to the road surface by bonding the magnetic marker, with one side retained by the liner, to the road surface and then peeling off the liner, and
the magnetic marker retained by the liner is divided into at least two regions by a continuous cut line penetrating in a thickness direction.
