差を得ることが可能な素材構成でなければならない。The resonance circuit is composed of a resistance R, an inductance L and an electrostatic capacity (capacitor capacity) C. The capacitor capacity C is formed of a plastic (resin) film which is a dielectric and spiral circuits formed on both sides thereof. The resistor R is formed of a metal foil, and the resistor R is formed of a metal foil forming a circuit. From these facts, in order to obtain the predetermined resonance frequency required for the resonance tag, it is necessary to have a material configuration capable of obtaining extremely accurate dimensions and their tolerances.

る。For the above reasons, the spiral circuit is conventionally made of a material in which a metal foil such as an aluminum foil is laminated on one side or both sides of a plastic film which is usually a dielectric, and is used as a printed wiring board. Similar to the manufacturing method described in (1), a metal foil on a plastic film is printed with an etching resistant ink in a predetermined pattern and etched with a chemical solution such as acid or alkali, or is formed by a photoresist etching method. However, this etching method using a chemical solution has a problem in that it takes a certain amount of time for the metal foil to dissolve and that the etching solution is discarded.

も容易でないという問題をも有する。As the conventionally used plastic film as a dielectric, an extruded film such as polyethylene is usually used, but it has various adjustment conditions such as the slit width of the molding die and the extrusion pressure of the resin. Therefore, there are problems that the lower limit of the thickness in terms of molding is limited and the tolerance of the thickness is limited. Lamination of these plastic films and metal foils, there is a method of thermocompression-bonding a semi-molten resin film extruded to the metal foil and a method of bonding the formed film to the metal foil with an adhesive, Any of these methods is likely to cause variations in the dielectric layer. Also, because the molded plastic film has a strong coating property, it is not easy to connect the circuit on the front and back of the plastic film for forming the resonance circuit, or the destruction of the resonance circuit (erasure of resonance characteristics).
Also has the problem that it is not easy.

Since other configurations are the same as those in FIG. 1, the same reference numerals are given and description thereof is omitted. In this example, the resin coating film 2a is described as a flat film, but since the resin liquid may be applied to the entire surface of the coiled aluminum foil to form the coating film, The shape may be such that the resin coating film exists between the coils, that is, a shape having a coil-shaped convex portion on a plane. By doing so, the insulating properties of the aluminum foil on both the front and back surfaces of the resin coating film can be more reliably ensured.

When the support 4 is a plastic film, the coil-shaped aluminum foil 3b provided with the coil-shaped resin coating 2 on one surface is attached to the support 4 by the resin coating 2, and then the resin coating 2 is formed. The resin coating film 2a may be formed by applying the resin liquid to the entire surface of the unsupported aluminum foil 3b including the surface of the support 4 which is visible between the coils.

In the figure, 10 indicates the position where the upper and lower aluminum foils are joined. By joining a large number as described above, it is possible to obtain a smaller resonant tag having a predetermined resonant characteristic.
