摘要： A magnetic field generating device includes a triaxial Helmholtz coil 3, amounting table 4 on which a portable device 2 is mounted, a current supplying part 5 and a controlling part 6. The current supplying part 5 supplies current I to individual three monoaxial Helmholtz coils 30 which construct the triaxial Helmholtz coil 3. The controlling part 6 changes the current flowing through the individual monoaxial Helmholtz coils 30 in such a manner that a synthetic magnetic field of a magnetic field generated within the triaxial Helmholtz coil 3 by the current I and an external magnetic field which acts from the outside into the triaxial Helmholtz coil 3 acts on a triaxial magnetic sensor 20 within the portable device 2 mounted on the mounting table 4 from a plurality of predetermined directions.

摘要： A sheet-shaped magnetic marker (1) 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 is divided into a plurality of regions in a matrix shape by a cut line (1C) cutting a magnet sheet (11) and a nonskid layer (181), with an adhesive layer being left. Thus, if peeling partially occurs, a region including the peeled part can be isolated, and expansion of peeling can be prevented.

摘要： 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 has a magnet sheet (11) as a magnetism generation source and a wireless tag (2) which outputs information via wireless communication to the vehicle side. In the magnetic marker, the wireless tag (2) is interposed between a sheet (11A) and a sheet (11B) configuring the magnet sheet (11), and the entire wireless tag (2) is accommodated inside the magnet sheet (11).
