In this step B, when the second frame sheet 12A is joined to the other surface 17b of the second base sheet 17A, the second base sheet is prevented from causing dimensional defects due to heat shrinkage of the adhesive. In order to improve the dimensional stability of the 17A and the second frame sheet 12A, it is preferable to reduce the amount of the adhesive used, and the second frame can be applied to the second base sheet 17A without using an adhesive. It is more preferable to heat-seal the sheet 12A.
Further, in this step B, the pair of through holes 17c of the second base sheet 17A and the pair of through holes 12c of the second frame sheet 12A are overlapped. Thereby, the second frame sheet 12A can be positioned with respect to the second base sheet 17A.

 Next, as shown in FIG. 8, the laminated sheet composed of the first base sheet 16A and the first frame sheet 11A is cut along the reference lines 11c and 11d (reference lines 16d and 16e) to obtain individual pieces. (Divide).

 Further, as shown in FIG. 9, the laminated sheet composed of the second base sheet 17A and the second frame sheet 12A is cut along the reference lines 12d and 12e (reference lines 17d and 17e) to obtain individual pieces. (Divide).

 Next, as shown in FIG. 10, the adhesive 15A discharged from the nozzle or the like of the adhesive application device is applied into the fitting portion 11a of the first frame sheet 11A bonded to the first base sheet 16A (step E). .

As the adhesive 15A, the same adhesive as that for forming the adhesive layer 15 is used.
Further, the amount of the adhesive 15A applied to the insertion portion 11a of the first frame sheet 11A is not particularly limited, but depending on the size of the module 14, the size and depth of the insertion portion 11a of the first frame sheet 11A, etc. Adjust as appropriate.

 Next, as shown in FIG. 11, the module 14 having the display element 13 is inserted into the insertion portion 11a of the first frame sheet 11A joined to the first base sheet 16A (step C).

In this step C, the module 14 is inserted into the insertion portion 11a of the first frame sheet 11A so that the display portion 13a of the display element 13 is disposed at a position facing the non-printing portion 18a of the first base sheet 16A. To do.
Moreover, in this process C, the adhesive 15A is developed between the first base sheet 16A and the module 14 by pressing the module 14 against the first base sheet 16A.
At this time, half of the module 14 is inserted into the insertion portion 11a of the first frame sheet 11A in the thickness direction of the module 14 in a portion other than the display element 13, and in the thickness direction of the display element 13, All the display elements 13 are inserted.

 Next, as shown in FIG. 12, the surface of the first frame sheet 11A opposite to the surface facing the first base sheet 16A (the surface facing the second base sheet 17A and the second frame sheet 12A) 11g In addition, on the surface 14a opposite to the surface facing the first base sheet 16A of the module 14 (the surface facing the second base sheet 17A and the second frame sheet 12A) 14a, the nozzle of the adhesive application device, etc. The adhesive 15B discharged from is applied (step F).

As the adhesive 15B, the same adhesive as that for forming the adhesive layer 15 is used.
Also, adhesion to the surface 11g of the first frame sheet 11A opposite to the surface facing the first base sheet 16A and the surface 14a opposite to the face of the module 14 facing the first base sheet 16A. The application amount of the agent 15B is not particularly limited, but is appropriately adjusted according to the size of the module 14 and the size and depth of the fitting portion 12a of the second frame sheet 12A.

 Next, as shown in FIGS. 12 and 13, the first frame sheet 11 </ b> A and the module 14 are joined to the second base sheet 17 </ b> A via the adhesive 15 </ b> B applied to the first frame sheet 11 </ b> A and the module 14. The two frame sheets 12A are overlapped, the module 14 is inserted into the insertion portion 12a of the second frame sheet 12A, and the contact portion 12b of the second frame sheet 12A is brought into contact with the back surface 13b of the display element 13 of the module 14. At the same time, the first frame sheet 11A and the second frame sheet 12A are butted and joined (step D).

In this step D, the through hole 16c of the first base sheet 16A and the through hole 11b of the first frame sheet 11A are overlapped with the through hole 17c of the second base sheet 17A and the through hole 12c of the second frame sheet 12A. The second frame sheet 12A joined to the second base sheet 17A is superimposed on the first frame sheet 11A and the module 14 so as to match. That is, the through hole 16c of the first base sheet 16A, the through hole 11b of the first frame sheet 11A, the through hole 17c of the second base sheet 17A, and the through hole 12c of the second frame sheet 12A communicate with each other. The second frame sheet 12A joined to the second base sheet 17A is superposed on the first frame sheet 11A and the module 14.
Thereby, the outline 18b of the printing layer 18 provided on the one surface 16a of the first base sheet 16A and the outline 19a of the printing layer 19 provided on the one surface 17a of the second base sheet 17A are overlapped. Can be matched.

Further, in this step D, the second frame sheet 12A joined to the second base sheet 17A is pressed against the first frame sheet 11A and the module 14 so that the second base sheet 17A and the module 14 are pressed. The adhesive 15B is developed between the first frame sheet 11A and the second frame sheet 12A.
In this step D, the excess of the adhesive 15B developed between the second base sheet 17A and the module 14 and between the first frame sheet 11A and the second frame sheet 12A is replaced with the first frame sheet 11A and The second frame sheet 12A is spread on the outer edge so as to expand. Thereby, the surplus part of the adhesive 15B is provided in the grooves 11e, 11e, 11f, 11f provided on the outer edge of the first frame sheet 11A and / or the grooves 12f provided on the outer edge of the second frame sheet 12A. , 12f, 12g, 12g. As a result, an amount of the adhesive 15B necessary for the joining between the second base sheet 17A and the module 14 and between the first frame sheet 11A and the second frame sheet 12A exists. .
At this time, half of the module 14 is inserted into the insertion portion 12a of the second frame sheet 12A in the thickness direction of the module 14 at a portion other than the display element 13.

 Next, the laminate composed of the first base sheet 16A, the first frame sheet 11A, the adhesive 15A, the module 14, the adhesive 15B, the second frame sheet 12A, and the second base sheet 17A is subjected to pressure treatment and bonding. By curing the agent (for example, heating, ultraviolet irradiation, electron beam irradiation, aging (the process of leaving it to cure with time)) (pressure treatment and adhesive curing process) The adhesives 15A and 15B are cured to form the adhesive layer 15 and to integrate the laminate.

 Next, as shown in FIG. 14, the laminate composed of the first base sheet 16 </ b> A, the first frame sheet 11 </ b> A, the adhesive layer 15, the module 14, the second frame sheet 12 </ b> A, and the second base sheet 17 </ b> A The information medium 10 is obtained by cutting along the outline 10a of the medium 10 (the outline 18a of the print layer 18a and the outline 19a of the print layer 19a).

 In this step, the excess of the adhesive 15B is also separated and removed by cutting the laminate.

According to the method of manufacturing the information medium of this embodiment, the first frame sheet 11A bonded to the first base sheet 16A and the second frame sheet 12A bonded to the second base sheet 17A are used to form the first frame. Since the module 14 is provided between the sheet 11A and the second frame sheet 12A, the position of the module 14 in the thickness direction can be stabilized and the manufacturing time can be shortened.
In addition, since the information medium 10 having a substantially symmetric structure can be manufactured with the joint (boundary line) between the first frame sheet 11A and the second frame sheet 12A as a boundary, in the obtained information medium 10, It is possible to prevent thermal shrinkage caused by the difference in thickness between the first base material 16 joined with the one frame 11 and the second base material 17 joined with the second frame 12. Therefore, the obtained information medium 10 is excellent in dimensional stability and does not cause appearance defects such as wrinkles due to shrinkage.
