等の問題点があつた。(Prior art) A method for guiding visually impaired people or a method for controlling the operation of vehicles by detecting ferrite as a magnetic marker (Patent application No. 55-61435)
No. 55-087597, patent application No. 55-087598,
The magnetic marking material in Japanese Patent Application No. 55-087598) is one or a mixture of magnetic powder such as ferrite, various asphalts, resins, etc.
Shows water impermeability. Because of this impermeability, when magnetic signs to guide visually impaired people are installed on sidewalks, passageways, etc., if the pavement is made permeable for general sidewalks, there will be poor drainage, and immediately after rain, a water film on the surface Therefore, it had the disadvantage that it was slippery, making it dangerous for visually impaired people, elderly people, etc. to walk on it. Furthermore, magnetic markers for controlling the operation of vehicles and the like are installed at golf courses, factories, amusement parks, and the like. When laying magnetic markers on the lawn at a golf course, it not only obstructs the plates but also looks bad, so as a countermeasure, the method of laying them under the lawn as shown in Figure 1 is recommended. However, with the conventional water-impermeable magnetic markings mentioned at the beginning, the supply of moisture from the lower layer to the grass directly above them is insufficient, inhibiting the growth of the grass, and causing significant local damage to the grass. There were problems such as weakening and withering.

記の欠点を解消する事を目的とするものである。(Problems to be Solved by the Invention) The purpose of the present invention is to solve the above-mentioned drawbacks by making the magnetic marker water permeable.
（問題点を解決するための手段）
本考案は、フエライトを主成分とする磁気標識
体内部に連孔空隙が形成されたものである。(Means for Solving the Problems) In the present invention, continuous holes are formed inside a magnetic marker whose main component is ferrite.

る。(Example) Powdered ferrite may be granulated into similar shapes and solidified and molded with one or more binders such as various asphalts, resins, emulsions, etc. To explain this with a diagram, 2 is a continuous void, 1 is a ferrite particle, and 3 is a binder. Rainwater flows through the continuous holes 2 from the top surface to the bottom surface or side surfaces.
In addition, when buried in soil, permeated water is retained in the continuous pores, and moisture is supplied from the lower layer to the upper layer through the continuous pores by capillary action, water vapor, etc.

示す。(Effects of the invention) According to the invention, drainage of magnetic signs placed on pavement surfaces of sidewalks, roads, etc. during and immediately after rain can be significantly improved, and the risk of slipping can be eliminated. In addition, even when buried under the lawn of a golf course, etc., the grass directly above the magnetic marker receives water through the water-permeable magnetic marker, so it grows on par with areas where no magnetic marker is embedded. shows.
