[0003] However, among the above-described antenna forming methods, the sensitivity of the formed antenna is relatively high by the metal deposition method. If the unevenness is present, the unevenness is formed on the metal-deposited surface directly under the influence of the surface condition, so that the disturbance of the electromagnetic field distribution is increased and the sensitivity of the antenna is reduced. In addition, the above-mentioned etching method is a method for easily forming an antenna shape arbitrarily, but involves many work steps such as application of a resist agent, pattern formation on the resist agent, and etching with an etching solution, which requires expensive equipment work. The environment is also required, raising the production cost. Then, it is necessary to safely treat a large amount of waste liquid generated during the etching step. Although the antenna formed by the coil bonding method has excellent sensitivity, the workability is poor because the metal coil is directly bonded to the surface of the holding base. In addition, there is a problem that there are many difficulties in securely bonding the metal coil to the holding base, and the productivity is poor. In the conductive ink printing method, the antenna shape can be arbitrarily formed using a printing method and the workability is good, but there is a problem that the antenna sensitivity is inferior because a non-conductive substance such as an ink vehicle is mixed. Was. Therefore, the present inventors have paid attention to the point that a metal vapor deposition layer having a smooth surface can be obtained by transferring the metal vapor deposition layer by a transfer method, and in view of this, the present invention has The task is to form the antenna by transferring a metal deposition layer.
An object is to obtain a highly sensitive antenna at low cost.

As described above, when forming the antenna 4, the metal deposition layer 8 a is formed on the surface of the holding base 2 via the adhesive 9.
Therefore, even if the surface of the holding base 2 has irregularities, the adhesive 9 which is in a soft state at the time of bonding is applied to the holding base 2 with a certain thickness (application thickness). As a result, the shape of the unevenness is leveled, and the shape of the unevenness of the holding base 2 does not break the smoothness of the metal deposition layer 8a. Further, the transferred metal vapor-deposited layer 8a itself has been vapor-deposited and formed on the transfer base material 7 in advance, and the surface on the transfer substrate 7 side when the metal-deposited transfer sheet 6 is peeled off. Appear as a smooth surface, and the surface of the metal deposition layer 8a transferred to the holding base 2 is further smoothed. Then, a non-contact IC is attached to one side of the holding base on which the antenna is formed.
Arrange the module and connect with the antenna, etc.
As shown in FIG.
Is attached via the adhesive 10 to obtain a non-contact IC card.

As described above, the present invention relates to a method for forming an antenna made of a metal-deposited layer via an adhesive on a holding base for arranging a non-contact IC module. An adhesive is applied in an antenna-shaped pattern, a metal-deposited transfer sheet obtained by metal-depositing a transfer substrate is bonded to a holding base via the adhesive, and after the adhesive is cured, the metal-deposited transfer sheet is peeled off. The metal-deposited layer of the metal-deposited transfer sheet is transferred to the holding base in an antenna-shaped pattern. As described above, the metal-deposited transfer sheet is used to transfer the metal-deposited layer to the holding base in an antenna-shaped pattern via an adhesive, so that the unevenness on the surface of the holding base is absorbed by the adhesive. The effect of the irregularities does not appear on the transferred metal vapor deposition layer side, and even in the metal vapor deposition layer itself, the surface away from the transfer substrate with a uniform thickness is smooth and smooth. This provides an effect that is excellent in practicality, for example, the holding base can easily form an antenna having a surface.
