2. Description of the Related Art It is said that the damage caused by unauthorized removal of goods from retail stores such as department stores and supermarkets and public facilities such as libraries is increasing year by year. In addition, it is said that with the miniaturization of computer discs, the number of discs into which important information is input without permission is increasing. In order to prevent these from being taken out without permission, so-called theft prevention, metal products in the shape of strips, wires, foils, thin films, etc. are held between paper or film, etc. A magnetic system is applied that detects changes in a magnetic field generated by a metal material when an article passes through a detection area provided at an exit of a storage area, an exit of a storage location, or the like.

However, attaching the anti-theft label to the outside of the package of the product has a problem that the label can be easily recognized by the shoplifter and the anti-theft label can be broken or peeled off. For this reason, recently, there is a tendency to enable the attachment of anti-theft labels inside the packaging of products. However, conventional anti-theft labels are manufactured by punching into a predetermined shape after the metal material and the paper or film that holds it are laminated, and therefore the metal material is exposed from the edges of the paper or film. Is in a state of
According to the Food Sanitation Law, there is a problem in that it is impossible for a product, particularly a food product, to be directly or indirectly contacted with the food product and the anti-theft label to be packaged in the package of the product.

In addition, the anti-theft label in which the metal material is exposed as described above is formed by a film or plastic.
Further, there are some cases where the metal material is not exposed by laminating, but it takes time and labor to laminate using a film or plastic, and it is very expensive. Furthermore, the laminated anti-theft label cannot be attached to the product as it is, and there is a problem that even if it is used by inserting it in the package of the product, it is taken out by a shoplifter. .

As described above, since the conventional anti-theft label is manufactured by punching, the metal material is clearly exposed from the edge of the label.
In Japanese Patent Publication No. 98, when manufacturing an anti-theft label using an amorphous metal thin wire, the traveling speed of the amorphous metal thin wire is described.
Described is a method of producing a slower than the running speed of an upper surface tape and a lower surface tape for holding an amorphous metal thin wire,
As a result, the end of the amorphous metal thin wire could be held inside the anti-theft label. FIG. 4 is a partial plan view showing the anti-theft label obtained by this method. However, even in the case of this anti-theft label, when the amorphous metal thin wire 1 is cut to a predetermined size by the wire cutting roller, the upper and lower surface tapes have an opening portion 7 as a cut flaw, and the lower surface tape is opened. Although the hole 7 is hidden by being attached to the product, the end of the amorphous metal thin wire 1 inside the anti-theft label is exposed from the hole 7 of the upper surface tape.
