Claim 12:
13. 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 comprises a wireless tag which outputs information via wireless communication to the vehicle side, the wireless tag including a processing circuit for processing information and a primary antenna electrically connected to the processing circuit so as to be able to transmit and receive information-superposed radio waves, and
the cut line is formed as avoiding at least the processing circuit and the primary antenna.
