Although the above-mentioned conventional magnetic guide rails are highly creative, they have many problems as described below when they are actually manufactured. That is, as a conventional magnetic guide rail, a rail A1 having a predetermined shape is prepared in advance, the rail A1 is embedded in the upper surface of the rail plate A, and further, the appearance, durability, safety, etc. of the rail portion are taken into consideration. Since it is manufactured through a plurality of steps of covering the rail A1 embedded as necessary with the same material as the base material of the rail plate, the manufacturing cost is high and the cost for manufacturing a mold such as the rail A1 is also high. Needed. Also,
Since the rail plate A needs a certain thickness, the raw material cost is high. Furthermore, according to the conventional method, the magnetic guide rail cannot be formed on a thin base material such as paper or plastic film, and the form of the completed magnetic guide rail is limited.

By the way, in order to mix and stir the ultrafine iron powder in the coating material, the particle size of the ultrafine iron powder needs to be 4 to 50 microns. Such fine iron powder is not generally commercially available. Therefore, powders of inorganic iron salts such as ferric sulfate, ferric chloride, ferric nitrate, and ferric acetate are pulverized into finer powders, which are mixed with a reducing agent aqueous solution to form iron powders. Ultrafine iron powder is obtained by precipitating and extracting the precipitated iron powder. As the reducing agent, low sodium sulfite, stannous chloride, sodium formate or the like is used.

The mixing ratio of the ultrafine iron powder and the paint is generally about 6: 4, but it is necessary to change the ratio somewhat depending on the surface roughness of the base material. For example, when the surface of the base material is smooth, the ratio of ultrafine iron powder may be smaller than the above.
