Description

 The present invention relates to a non-contact type data receiver / receiver that can receive information from the outside using electromagnetic waves or radio waves as a medium, and can transmit information to the outside, such as an information recording medium for RFID (Radio Frequency IDentification). And the manufacturing method thereof.

 An IC tag, which is an example of a non-contact type data receiving / transmitting body, includes an inlet including a base material, and an antenna and an IC chip that are provided on one surface and connected to each other. In an IC tag, when an electromagnetic wave or radio wave from an information writing / reading device is received, an electromotive force is generated in the antenna by a resonance action. Then, the IC chip in the IC tag is activated by this electromotive force, information in the IC chip is converted into a signal, and this signal is transmitted from the antenna of the IC tag.

In order to make such an IC tag excellent in heat resistance, weather resistance and flexibility, various packaged IC tags have been studied.
For example, an inlet is stored in a storage portion (storage space) provided in a casing made of silicone resin, polytetrafluoroethylene resin, or the like, and the storage section storing the inlet is sealed with a material similar to that of the casing. An IC tag sealed with a stop member is known (for example, see Patent Document 1).
Further, an IC tag in which an inlet is molded only with a resin such as an epoxy resin and packaged is known (see, for example, Patent Document 2).
Further, there is known an IC tag in which a thin sheet-like circuit portion is sandwiched by a surface base material made of a urethane resin coated with a silicone film via an adhesive, and these are integrated (for example, patents) Reference 3).

 However, when the inlet is stored in the casing, there is a problem that it is difficult to reduce the thickness of the IC tag itself because a certain thickness of the casing is necessary to secure the strength of the casing. Moreover, when manufacturing such an IC tag, since it is necessary to store and arrange | position an inlet separately in a housing | casing, there existed a problem that manufacturing efficiency was low.

 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a manufacturing method of a non-contact type data transmitter / receiver that is thin, excellent in flexibility, and can be easily manufactured.

 The non-contact type data transmitting / receiving body manufacturing method of the present invention includes an inlet and a covering material that covers at least a surface of the inlet where the IC chip is provided, and the covering material is a two-component curable urethane-based adhesive. A method for producing a non-contact type data receiving / transmitting body made of an agent, the step of applying an adhesive made of a two-component curable urethane adhesive on a release layer forming one surface of the first transport belt A and the surface of the first transport belt provided with the IC chip on the inlet are overlaid on one surface of the first transport belt with the adhesive applied to the first transport belt, and the first transport belt. The process B has a step B of unfolding the adhesive between the first conveyor belt and the inlet by pressing the inlet.

 After the step B, a step C of applying an adhesive made of a two-component curable urethane-based adhesive on the surface of the inlet opposite to the surface on which the IC chip is provided, and the inlet applied to the inlet A second conveyor belt is overlaid on the surface of the inlet opposite to the surface on which the IC chip is provided via an adhesive so that the release layer forming one surface is opposed to the inlet. By pressing the second transport belt against the surface, the adhesive is spread between the surface of the inlet opposite to the surface on which the IC chip is provided and the second transport belt. It is preferable to have Step D.

 According to the method for manufacturing a non-contact type data receiving / transmitting body of the present invention, an adhesive and an inlet made of a two-component curable urethane adhesive are laminated on the release layer forming one surface of the first transport belt. Since an integrated laminate is formed, it is not necessary to use a release substrate to spread the adhesive on the surface of the inlet where the IC chip is provided. The process of peeling the material is not necessary, and the manufacturing process can be simplified.

Then, the adhesive 12A discharged from the nozzle 41 of the adhesive application device is applied linearly (step A).

As adhesive 12A, the thing similar to the adhesive which forms said coating | covering material 12 is used.
Further, the width for applying the adhesive 12A to the one surface 21a of the first conveying belt 21, that is, the amount of the adhesive 12A applied to the one surface 21a of the first conveying belt 21 is not particularly limited. Depending on the size and number of IC chips 15 and antennas 16 provided on the inlet sheet 31 covered with the adhesive 12A, the thickness required for the covering 12 formed by curing the adhesive 12A, etc. And adjusted as appropriate.

As the first conveying belt 21, one in which one surface 21a is made of a release layer and the surface of the release layer is processed into an uneven surface by embossing or the like is preferably used.
That is, as the first conveyor belt 21, one having a large number of dot-like convex portions 21A on one surface 21a and the one surface 21a forming an uneven surface is preferably used.
In this embodiment, as the 1st conveyance belt 21, the one surface 21a has illustrated the uneven | corrugated surface.

Further, the dot-shaped convex portions 21 </ b> A are regularly or irregularly formed on one surface 21 a of the first transport belt 21.
The point-shaped convex portions 21A are regularly formed on the one surface 21a of the first conveying belt 21 so that the large number of convex portions 21A are substantially the same size and at regular intervals (periods). In fact) that is formed.
On the other hand, the point-shaped convex portions 21 </ b> A are irregularly formed means that a large number of convex portions 21 </ b> A are formed with irregular sizes and intervals on one surface 21 a of the first transport belt 21. Say.
Moreover, the magnitude | size and space | interval of the convex part 21A are not specifically limited, According to the adhesiveness of the adhesive agent 12A, etc., it adjusts suitably.

As the 1st conveyance belt 21, what provided the peeling layer with a thickness of 1 micrometer-50 micrometers which consists of silicones on the one side of the base material which consists of polyurethane, a synthetic rubber, etc. is used.
That is, one surface 21a of the first transport belt 21 is composed of a release layer made of silicone.
The peeling force of the first transport belt 21 is 0.05 to 1.0 N / 50 mm.

 As described above, in the process A, the adhesive 12 </ b> A is applied on the release layer (not shown) forming the one surface 21 a of the first transport belt 21.

 Next, as shown in FIG. 2 and FIG. 4, the inlet sheet 31 conveyed in the direction of the arrow in the figure is the first at a portion where the pair of rollers 42 and 43 that rotate in the direction of the arrow in the figure face each other. The first conveying belt 21 is superposed on one surface 21a of the first conveying belt 21 being conveyed in the direction of the arrow in the figure via the adhesive 12A applied to one surface 21a of the conveying belt 21. By pressing the inlet sheet 31 against the belt 21, as shown in FIG. 5, one surface 21 a of the first conveying belt 21 is formed over almost the entire area between the first conveying belt 21 and the inlet sheet 31. The adhesive 12A applied to the substrate is developed (step B).

 In this process B, one surface 14a of the base 14A, that is, the surface of the inlet sheet 31 on which the IC chip 15 and the antenna 16 are provided (hereinafter referred to as “one of the surfaces 21a of the first conveying belt 21”). The inlet sheet 31 is overlapped on one surface 21a of the first conveyor belt 21 so that the surface 31a faces the surface 31a.

 In Step B, as described above, the adhesive 12A made of a two-component curable urethane adhesive that is cured by the reaction of the main agent and the curing agent without applying external conditions is used. Therefore, the adhesive 12A has fluidity until the adhesive 12A is developed between the first conveying belt 21 and the inlet sheet 31, but gradually loses fluidity as the reaction progresses. It hardens. Thus, the one surface 31a of the inlet sheet 31 and the IC chip 15 and the antenna 16 provided on the one surface 31a are covered with the adhesive 12A. When the adhesive 12A is cured, the coating material 12 is obtained.

 Further, in step B, the thickness of the adhesive 12A after being developed between the first conveyor belt 21 and the inlet sheet 31 is bonded to at least unevenness caused by the IC chip 15 and the antenna 16 of the inlet sheet 31. Of the agent 12A so that it does not appear on the surface 12a opposite to the surface in contact with the inlet sheet 31, and the IC chip 15 and the antenna 16 are not damaged by an external impact, for example, within a range of 10 μm to 2000 μm. And

In step B, the force (pressure) for pressing the inlet sheet 31 against the first conveyor belt 21 is not particularly limited, and the thickness, size, and adhesion of the first conveyor belt 21 and the inlet sheet 31 are not limited. depending on the coating amount of the agent 12A, it is suitably ^adjusted, is preferably ^{1kg / cm 2 ~20kg / cm 2} , more preferably ^{5kg / cm 2 ~10kg / cm 2} .

By this step B, the IC chip 15 and the antenna 16 are completely covered with the adhesive 12A, and the adhesive 12A is filled between the first transport belt 21 and the inlet sheet 31 with almost no gap.
Further, the uneven shape of the one surface 21a of the first transport belt 21 is transferred to the surface in contact with the one surface 21a of the first transport belt 21 in the adhesive 12A.

 In order to accelerate the curing reaction of the adhesive 12 </ b> A, a heating device such as a heater is provided after the rollers 42 and 43 (along the conveying direction), and deployed between the first conveying belt 21 and the inlet sheet 31. The adhesive 12A thus obtained may be heated to a predetermined temperature.

Further, the adhesive 12A is applied to the one surface 21a of the first conveyance belt 21 until reaching the end of the first conveyance belt 21 and the second conveyance belt 22 on the third conveyance belt 23 side. Curing is almost completed during this period. Therefore, at the point where the first conveyor belt 21 and the second conveyor belt 22 are separated (the end of the first conveyor belt 21 and the second conveyor belt 22 on the third conveyor belt 23 side), the first conveyor belt 21 and the second conveyor belt 22 are separated. The cured adhesive 12 </ b> A is peeled off from the transport belt 21.
In addition, a roller for sandwiching the laminate made of the adhesive 12A and the inlet sheet 22 between the third conveyor belt 23 is provided at a position facing the roller for rotating the third conveyor belt 23. It has been. The cured adhesive 12 </ b> A is peeled off from the first transport belt 21 and the laminate is transported by the torque caused by the sandwiching.

Next, as shown in FIGS. 2 and 6, the laminated body transferred to the third conveyor belt 23 by the first conveyor belt 21 and the second conveyor belt 22 is cut into a cutting blade of a cutting device. 44 is cut in accordance with the shape of the antenna 16 in the thickness direction (along the one-dot chain line in FIG. 6), and the laminate is separated into pieces (step E), and the non-contact type data shown in FIG. The transmission / reception body 10 is obtained.
Here, cutting the laminated body according to the shape of the antenna 16 means cutting the laminated body according to the shape of the target non-contact type data receiving / transmitting body 10 without damaging the antenna 16.

According to the manufacturing method of the non-contact type data transmitting / receiving body of this embodiment, the adhesive 12A is applied on the release layer forming the uneven surface on the one surface 21a of the first transport belt 21, and the first Since the adhesive 12 </ b> A and the inlet sheet 31 are laminated and integrated on the conveyance belt 21 to form a laminated body, the uneven surface of the first conveyance belt 21 is transferred to one surface 12 a of the covering material 12. The non-contact type data receiving / transmitting body 10 can be obtained.
In addition, since one surface 21a of the first conveying belt 21 forms a release layer, it is not necessary to use a release substrate in order to spread the adhesive 12A on the one surface 31a of the inlet sheet 31. Further, after the adhesive 12A is cured, a process of peeling the peeling substrate is not necessary, and the manufacturing process can be simplified.

 Also, unlike the conventional case, it is not necessary to store the inlet in a resin casing and seal it with a sealing member made of the same material as the casing, or mold the inlet with resin. The contactless data receiving / transmitting body 10 can be easily manufactured. Furthermore, since no member other than the adhesive 12A is required to cover one surface of the inlet sheet 31, the contactless data receiving / transmitting body 10 having a very thin thickness can be manufactured. The manufacturing cost of the contact-type data receiving / transmitting body 10 can be reduced.

 In this embodiment, the case where the convex portion 21A is formed over almost the entire surface of the one surface 21a of the first conveyor belt 21 is illustrated, but the present invention is not limited to this. In the present invention, one surface of the first conveyor belt may be a flat surface. In this case, no convex portion is formed on one surface of the covering material of the obtained non-contact type data transmitting / receiving body, and the one surface forms a flat surface. Moreover, in this invention, the convex part may be partially formed in one surface of the 1st conveyance belt, and the abundance ratio of the convex part (area with respect to one surface of the 1st conveyance belt) The ratio is appropriately adjusted according to the adhesiveness of the adhesive.

 Moreover, in this embodiment, although the case where the above-mentioned non-contact type data receiving / transmitting body 10 was continuously manufactured using the elongate inlet sheet 31 was illustrated, this invention is not limited to this. In the present invention, a non-contact type data receiving / transmitting body may be individually manufactured using an inlet that has been separated into pieces.

 Moreover, in this embodiment, although the case where the process E was performed after the process B was illustrated, this invention is not limited to this. In the present invention, the process E does not have to be performed when, for example, an inlet that has been singulated in advance is used.

 Further, in the case of providing a protective film covering one surface 12a of the covering material 12 (one surface 10c of the non-contact type data receiving / transmitting body 10), before applying the adhesive 12A, the first conveying belt is previously provided. A protective agent for forming a protective film is applied to one surface 21 a of 21.

Further, the size and interval of the convex portions 55 are not particularly limited, and are appropriately adjusted according to the adhesiveness of the adhesive forming the first covering material 53.

In addition, on the surface 54a opposite to the surface in contact with the inlet 51 of the second covering material 54 (hereinafter referred to as “one surface”) 54a, a large number of dot-like convex portions 56 are formed. One surface 54a of the covering material 54 is an uneven surface.
The convex portion 56 forms part of the second covering material 54 and is made of an adhesive that forms the second covering material 54.

The dot-like convex portions 56 are regularly or irregularly formed on one surface 54 a of the second covering material 54.
The point-shaped convex portions 56 are regularly formed on the one surface 54a of the second covering material 54. The large number of convex portions 56 are substantially the same in size and at regular intervals (periods). In fact) that is formed.
On the other hand, the point-shaped convex portions 56 are irregularly formed means that a large number of convex portions 56 are formed in irregular sizes and intervals on one surface 54a of the second covering material 54. Say.
Moreover, the magnitude | size and space | interval of the convex part 56 are not specifically limited, According to the adhesiveness etc. of the adhesive agent which forms the 2nd coating | covering material 54, it adjusts suitably.

The inlet 51 is generally configured by a base material 57 and an IC chip 58 and an antenna 59 which are provided on one surface 57a of the base material 57 and are electrically connected to each other.
The antenna 59 is a dipole antenna composed of a pair of planar radiating elements 60 and 61 made of various conductors, facing each other and having feeding points (portions connected to the IC chip 58) on the facing sides. is there.
The length in the longitudinal direction of the antenna 59 corresponds to a half wavelength of the frequency (300 MHz to 30 GHz) of the ultra-high frequency band <UHF> and the microwave band that can be used for a non-contact IC module such as a non-contact IC card. It is the length to do. That is, the length in the longitudinal direction of the radiating elements 60 and 61 is a length corresponding to a quarter wavelength.

One surface 51 a of the inlet 51 corresponds to one surface 57 a of the base material 57, and the other surface 51 b of the inlet 51 corresponds to the other surface 57 b of the base material 57.
Therefore, on one surface 51 a of the inlet 51, the IC chip 58 and the antenna 59 are covered with the first covering material 53.

 Then, on the four side surfaces of the non-contact type data transmitting / receiving body 50, the end surface of the first covering material 53, the end surface of the base material 57, and the end surface of the second covering material 54 are the same surface. More specifically, for example, on the side surface 50a of the non-contact type data transmitting / receiving body 50, the end surface 53b of the first covering material 53, the end surface 57c of the base material 57, and the end surface 54b of the second covering material 54 are provided. They are on the same plane. Similarly, the end surface 53c of the first covering material 53, the end surface 57d of the base material 57, and the end surface 54c of the second covering material 54 are the same surface on the side surface 50b of the non-contact type data transmitting / receiving body 50. ing.

The thickness of the first covering material 53 is not particularly limited, but at least unevenness caused by the IC chip 58 and the antenna 59 of the inlet 51 appears on one surface (outer surface) 50c of the non-contact type data receiving / transmitting body 50. And the inlet 51 is not damaged by an external impact, for example, in the range of 10 μm to 2000 μm.
The thickness of the second covering material 54 is not particularly limited, but is such that the inlet 51 is not damaged by an external impact, and is, for example, in the range of 10 μm to 2000 μm.

 Furthermore, when the non-contact type data receiving / transmitting body 50 has sufficient flexibility (flexibility) and the non-contact type data receiving / transmitting body 50 is bent, the first covering material 53 is formed with respect to the inlet 51. In order to prevent the stress caused by the difference in thickness between the first covering material 54 and the second covering material 54, the thickness of the first covering material 53 is preferably equal to the thickness of the second covering material 54.

 The covering material 52 (the first covering material 53 and the second covering material 54) is in a liquid state before use, and the main agent and the curing agent can be used without applying external conditions such as heating, ultraviolet irradiation, and electron beam irradiation. It consists of a two-component curable urethane adhesive that cures by reaction.

 As the two-component curable urethane adhesive, the same one as in the first embodiment described above is used.

In the non-contact type data receiving / transmitting body 50, a large number of convex portions 55 are formed on one surface 53a of the first covering material 53, and the one surface 53a of the first covering material 53 forms an uneven surface. Therefore, even if they are overlapped with other similar sheet-like materials (IC tags or the like), they do not adhere to each other and are easy to handle. Moreover, since many convex parts 56 are formed in one surface 54a of the 2nd coating | covering material 54, and one surface 54a of the 2nd coating | covering material 54 has comprised the uneven | corrugated surface, it is another sheet-like thing of the same kind. Even if they are overlapped with an IC tag or the like, the contact area is small, they do not adhere to each other, and handling is easy. Therefore, even if a large number of non-contact type data receiving / transmitting bodies 50 are grouped, they are not in close contact with each other and are easy to handle.
In particular, the non-contact type data transmitting / receiving body 50 has one surface 50c and the other surface 50d having tack property (property that can be temporarily fixed) by the covering material 52 made of a two-component mixed urethane resin. However, since one surface 53a of the first covering material 53 forms an uneven surface, and one surface 54a of the second covering material 54 forms an uneven surface, it overlaps with other similar sheet-like materials. However, the contact area is small and they do not stick to each other.

 Furthermore, the non-contact type data receiving / transmitting body 50 can be easily manufactured because the one surface 51a and the other surface 51b of the inlet 51 are directly covered with the covering material 52. it can.

 In this embodiment, a convex portion 55 is formed over substantially the entire surface of one surface 53a of the first covering material 53, and a convex portion 56 is formed over the substantially entire surface of one surface 54a of the second covering material 54. Although the case where it formed was illustrated, this invention is not limited to this. In the present invention, the convex portion is not formed on one surface of the covering material, and the one surface may be a flat surface. Moreover, in this invention, the convex part may be partially formed in one surface of the coating | covering material, and the abundance ratio (area ratio with respect to one surface of a coating | coated material) of a convex part is coating material. It adjusts suitably according to the adhesiveness of the adhesive agent which forms.

 Moreover, in this embodiment, although the one surface 53a of the 1st coating | covering material 53 comprised an uneven surface, and illustrated the case where the one surface 54a of the 2nd coating | covering material 54 made an uneven surface, this invention Is not limited to this. In the present invention, only one surface of the first covering material may form an uneven surface.

Moreover, in this embodiment, although the case where the non-contact-type data transmission / reception body 50 has comprised the planar view substantially rectangular shape was illustrated, this invention is not limited to this. In the present invention, the non-contact data receiving / transmitting body may have an arbitrary card shape or tag shape when viewed in plan.
Moreover, although this embodiment illustrated the case where the inlet 51 which has the antenna 59 which consists of a dipole antenna comprised from a pair of planar radiation elements 60 and 61 was provided, this invention is not limited to this. In the present invention, the antenna may be a dipole antenna composed of a pair of frame-shaped radiating elements, a meander-shaped dipole antenna, a monopole antenna, or the like.

Accordingly, the first adhesive 53A has fluidity until it is developed between the first conveyor belt 71 and the inlet sheet 81, but gradually loses fluidity as the reaction proceeds. Finally, it hardens. Thereby, one surface 81a of the inlet sheet 81, and the IC chip 58 and the antenna 59 provided on the one surface 81a are covered with the first adhesive 53A. When the first adhesive 53A is cured, the first covering material 53 is obtained.

The thickness is appropriately adjusted according to the thickness required for the second covering material 54 formed by curing the second adhesive 54A.

 Next, as shown in FIGS. 8 and 12, the pair of layers that rotate in the direction of the arrow in the drawing and that forms the one surface 72 a of the second conveying belt 72 that rotates are conveyed in the direction of the arrow in the drawing. The laminated body that is conveyed in the direction of the arrow in the figure is configured through the second adhesive 54A applied to the other surface 81b of the inlet sheet 81 at the opposed portions of the rollers 95 and 96. As shown in FIG. 13, the inlet sheet 81 and the second conveyor belt 72 are overlapped on the other surface 81 b of the inlet sheet 81 and pressed against the inlet sheet 81 by pressing the second conveyor belt 72. The second adhesive 54A applied to the other surface 81b of the inlet sheet 81 is developed over almost the entire area between the first and second conveyor belts 71 and 7 (step D).

Accordingly, the second adhesive 54A has fluidity until it is developed between the inlet sheet 81 and the second conveyance belt 72, but gradually loses fluidity as the reaction proceeds. Finally, it hardens. Thereby, the other surface 81b of the inlet sheet 81 is covered with the second adhesive 54A. When the second adhesive 54A is cured, the second covering material 54 is obtained.

 In Step D, the thickness of the second adhesive 54A after being developed between the inlet sheet 81 and the second conveyor belt 72 is set to the thickness of the first conveyor belt 71 and the inlet sheet in Step B described above. The thickness is the same as the thickness of the first adhesive 53 </ b> A after being developed between 81, for example, in the range of 10 μm to 1000 μm.

In step D, the force (pressure) for pressing the second transport belt 72 against the inlet sheet 81 is not particularly limited, and the thickness and size of the laminate and the second transport belt 72 are not limited. depending on the coating amount of the second adhesive 54A, it is suitably ^adjusted, is preferably ^{1kg / cm 2 ~20kg / cm 2} , more preferably ^{5kg / cm 2 ~10kg / cm 2} .

By this step D, the second adhesive 54 </ b> A is filled between the inlet sheet 81 and the second transport belt 72 with almost no gap.
Further, the uneven shape of the one surface 72a of the second conveyance belt 72 is transferred to the surface of the second adhesive 54A that contacts the one surface 72a of the second conveyance belt 72.

In order to accelerate the curing reaction of the second adhesive 54A, a heating device such as a heater is provided after the rollers 95 and 96 (along the conveying direction), and the second conveying belt 72 and the inlet sheet 81 are The second adhesive 54A spread between them may be heated to a predetermined temperature.
The first adhesive 53A is applied to one surface 71a of the first transport belt 71 and then reaches the end of the first transport belt 71 and the second transport belt 72 on the third transport belt 73 side. Until almost complete. Also, the second adhesive 54A is applied to the other surface 81b of the inlet sheet 81 until reaching the end of the first conveyor belt 71 and the second conveyor belt 72 on the third conveyor belt 73 side. Curing is almost completed during this period. Therefore, at the point where the first conveyor belt 71 and the second conveyor belt 72 are separated (the end of the first conveyor belt 71 and the second conveyor belt 72 on the third conveyor belt 73 side), the first conveyor belt 71 and the second conveyor belt 72 are separated. The cured first adhesive 53 </ b> A is peeled off from the conveyor belt 71, and the cured second adhesive 54 </ b> A is peeled off from the second conveyor belt 72.

 In addition, the first adhesive 53A, the inlet sheet 81, and the second adhesive 54A are provided between the third conveyor belt 73 and a position facing the roller for rotating the third conveyor belt 73. The roller for pinching the laminated body which becomes is provided. With this torque, the cured first adhesive 53A is peeled off from the first transport belt 71, and the cured second adhesive 54A is peeled off from the second transport belt 72. The laminate is transported.

Next, as shown in FIGS. 8 and 14, the laminated body transferred to the third conveyor belt 73 by the first conveyor belt 71 and the second conveyor belt 72 is cut into a cutting blade of a cutting device. 97, cutting in accordance with the shape of the antenna 59 in the thickness direction (along the one-dot chain line in FIG. 14) to separate the stack (step E), and the non-contact type data shown in FIG. The transmission / reception body 50 is obtained.
Here, cutting the laminated body according to the shape of the antenna 59 means cutting the antenna 59 according to the shape of the target non-contact type data receiving / transmitting body 50 without damaging the antenna 59.

According to the manufacturing method of the non-contact type data transmitting / receiving body of this embodiment, the first adhesive 53A and the inlet sheet 81 are laminated on the release layer forming the uneven surface of the first transport belt 71, and After applying the second adhesive 54A on the inlet sheet 81, the release layer forming the uneven surface of the second conveyor belt 72 is superimposed on the inlet sheet 81 via the second adhesive 54A. Since the first adhesive 53A, the inlet sheet 81, and the second adhesive 54A are laminated and integrated between the first conveyor belt 71 and the second conveyor belt 72, a first laminated body is formed. The uneven surface of the first transport belt 71 is transferred to one surface 53a of the covering material 53, and the uneven surface of the second transport belt 72 is transferred to one surface 54a of the second covering material 54. Contactless data receiver / transmitter 0 can be obtained.
Further, since one surface 71a of the first transport belt 71 forms a release layer, it is necessary to use a release substrate in order to spread the first adhesive 53A on the one surface 81a of the inlet sheet 81. Since there is no, the process which peels the peeling base material after hardening of the 1st adhesive agent 53A becomes unnecessary, and can simplify a manufacturing process. Similarly, since one surface 72a of the second conveyor belt 72 forms a release layer, a release substrate is used to spread the second adhesive 54A on the other surface 81b of the inlet sheet 81. Since there is no need, the process of peeling the peeling base material after the curing of the second adhesive 54A becomes unnecessary, and the manufacturing process can be simplified.

 Also, unlike the conventional case, it is not necessary to store the inlet in a resin casing and seal it with a sealing member made of the same material as the casing, or mold the inlet with resin. The contactless data receiving / transmitting body 50 can be easily manufactured. Further, since no member other than the first adhesive 53A and the second adhesive 54A is required to cover both surfaces of the inlet sheet 81, the non-contact type data receiving / transmitting body 50 having a very thin thickness is manufactured. As a result, the manufacturing cost of the non-contact type data receiving / transmitting body 50 can be reduced.

 Moreover, in this embodiment, although the case where the surface where the surface of a peeling layer makes an uneven surface was used as the 2nd conveyance belt 72 in the process D was illustrated, this invention is not limited to this. In the present invention, in step D, the second transport belt may be one in which the surface of the release layer does not form an uneven surface.
