DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to FIG. 1 which is a schematic sectional view of a non-contact type IC label according to an embodiment of the present invention. Will be described. The configuration of the non-contact type IC label 1 of the present invention will be described. As shown in FIG. 1, a non-contact type IC label 1 includes an antenna substrate 3 having an IC 2 and a label 4 such as paper on a base material 5 such as a polyethylene terephthalate (PET) film. The substrate 3 is placed in the concave portion 8 having the window 7 formed on the first main surface 6 of the base material 5, and the IC 2 is placed in the window 7 from the side having the IC 2.
And the first main surface 6 and the surface of the antenna substrate 3 opposite to the surface on which the IC 2 is provided.
Having a protective member 10 with an adhesive layer 9 interposed therebetween.
It has a label 4 on the second adhesive layer 11 above and a third adhesive layer 13 on the second main surface 12 of the substrate 5. On the antenna substrate 3, a spiral antenna pattern (not shown) is formed on a surface having the IC 2, and its terminal portion is connected to the IC 2.

A method for manufacturing the non-contact type IC label 1 is shown in FIG.
The antenna substrate 3 on which the IC 2 is mounted and the label 4 such as paper are mounted on a base material such as a PET film, and have a window 7 on the first main surface 6 of the base material 5 as shown in FIG. The recess 8 is formed, and the antenna substrate 3 is
The IC 2 is embedded so as to be inserted into the window 7 from the side on which the IC 2 is mounted, and is opposite to the first main surface 6 where the antenna substrate 3 is embedded and the surface of the antenna substrate 3 on which the IC 2 is mounted. The protective member 10 is laminated on the surface using the first adhesive layer 9, the label 4 is laminated on the protective member 10 using the second adhesive layer 11, and the second main surface of the base material 5 It is produced by forming a third adhesive layer 13 on the second adhesive layer 12.

As the protective member 10, a PET film,
Examples thereof include a polyethylene naphthalate (PEN) film and a liquid crystal polymer film, but are not limited thereto, and any polymer film having moisture resistance may be used. Further, for the first adhesive layer, the second adhesive layer, or the third adhesive layer, a copolymer polyester or the like is used and is applied by a roll coater or the like.

EXAMPLES When the protective member of the present invention was applied to a non-contact type IC label similar to that of the above-described embodiment, the following reliability test was conducted. As a protective member, a PET film, a PEN film, or a liquid crystal polymer film was used. After leaving the non-contact type IC label 1 for 2 weeks in an environment of 40 ° C. and 95% RH, a case where the transmission frequency deviated from the frequency of 13.56 MHz before the test by 0.2 Hz was regarded as NG. Table 1 shows the test results.

[0013]

[Table 1]

From the above test results, in order to maintain reliability, the thickness of the polymer film of the protective member 10 must be 10
μm or more, the first adhesive layer 9
Since the workability when applying and affixing to the substrate 5 is poor, the thickness is preferably 25 μm or more.

The above-mentioned non-contact type IC label 1 has a structure in which a label 4 such as paper is attached on a protective member 10.
If it is possible to write on the polymer film of the protective member 10 with a pen or the like, it is not necessary to use the label 4.
