MAGNETIC MARKER AND MAGNETIC MARKER USING METHOD

A magnetic marker () to be laid on a traveling road where a vehicle travels includes a circular sheet-shaped magnet sheet (), which is a magnet as a magnetism generation source, having a diameter of 100 mm, and a reflective sheet () forming a reflecting part which retroreflects laser light from a lidar unit mounted on the vehicle and is laminated on a surface of magnet sheet (). Since the magnetic marker is detectable not only magnetically by a magnetic sensor but also by a lidar unit using laser light, the magnetic marker is easily detected compared with a general magnetic marker that is detectable only magnetically.
