Document Type and Number:
WIPO Patent Application WO/2019/239825
Kind Code:
A1
Abstract:
When constructing, on the road surface (30S) of a road, a magnetic marker (1) in which an RFID tag (2) equipped with an antenna for wireless communication is held on the outer periphery thereof, performing the following steps makes it possible to maintain high communication performance in the RFID tag (2) even when the area around the constructed magnetic marker (1) is submerged in water: an arrangement step in which the magnetic marker (1) is housed in a housing hole (31) drilled in the road surface (30S); and a formation step in which a protective section (40) for isolating the antenna from water is provided to the magnetic marker (1).
