In these card-type information media such as IC cards and magnetic cards, information is written and read using a dedicated device.
Such a card-type information medium includes a module having a display section for displaying information or a light emitting section for emitting light (hereinafter collectively referred to as “output section”). In this information medium, a frame is used to arrange the module at a predetermined position with respect to the base material. That is, this information medium has a structure in which a frame in which a module is installed at a predetermined position is sandwiched between a pair of base materials via an adhesive (for example, see Patent Documents 1 and 2).

In the information medium as described above, the output part of the module is adhered to the window part (the part not printed or the non-printing part) of the base material by a transparent adhesive.
As described above, when the module and the base material are bonded to each other through the adhesive, air enters between the adhesive and the base material, and the air may become bubbles and remain in the output unit. When bubbles are present in the display unit, display is hindered, and display contents are difficult to visually recognize. Further, when bubbles exist in the light emitting portion, there is a problem that light emission is hindered and a predetermined luminance cannot be obtained.

 The present invention has been made in view of the above circumstances, and provides an information medium in which bubbles are prevented from being present in an adhesive for bonding and fixing them in an output part of a module, and a method for manufacturing the same. For the purpose.

 The information medium of the present invention includes a frame, a module provided in the frame and having an output unit, an adhesive covering at least the output surface of the output unit and its vicinity, and the surface on the output surface side of the frame. An information medium comprising a layer and a pair of base materials sandwiching the frame and the module while being in contact with the adhesive layer, wherein the output unit is at least partially in contact with the frame, A space is provided in the frame, and a space in which the adhesive layer is formed is provided between the output portion and the frame.

 An information medium manufacturing method of the present invention includes a frame, a module provided in the frame and having an output unit, at least an output surface of the output unit and its vicinity, and a surface on the output surface side of the frame. An adhesive layer to be coated; and a pair of base materials that are in contact with the adhesive layer and sandwich the frame and the module, wherein the output unit is attached to the frame so that at least a part thereof abuts the frame. A method for manufacturing an information medium provided with a space in which the adhesive layer is formed between the output unit and the frame, wherein the module is inserted into one side of the first substrate. A step A in which at least a part of the output portion of the module abuts and a frame is provided between the output portion and the insertion portion. Step B for inserting the module into the insertion portion, Step C for applying an adhesive to the surface opposite to the surface of the frame and the module facing the first base, and the adhesive. The frame and the module are overlapped with one surface of the second base material, and the second base material is pressed against the frame and the module. A step D in which the adhesive is spread between the base material and the adhesive and the air that has entered the space between the second base material and the output portion are caused to flow into the space. And the step A and the step B are performed in random order.

 According to the information medium of the present invention, the output part of the module is installed in the frame so that at least a part thereof abuts the frame, and a space in which an adhesive layer is formed is provided between the output part and the frame. Therefore, when the frame and module and the base material are overlapped, the air (bubbles) that entered between the output part and the base material is moved into the space, and the moved air is moved to the position. It can be fixed so that it does not move. Therefore, since there are no bubbles between the output part and the substrate, the output part is excellent in visibility. Further, since a part of the output part of the module is inscribed in the frame, the output part is accurately positioned with respect to the base material, so that the visibility of the output part can be improved.

 According to the information medium manufacturing method of the present invention, in step D, the second base material is superimposed on the frame and the module via the adhesive, and the second base material is pressed against the frame and the module. By expanding the adhesive between the frame and the module and the second base material, the adhesive and between the second base material and the output part are placed in the space between the frame and the output part. Since the adhesive is cured after flowing in the air that has entered, the air moved into the space can be fixed so as not to move from the position. Therefore, there is no bubble between the output unit and the second base material, and an information medium excellent in the visibility of the output unit can be obtained.
