Description

Next with the structure and then with the receiving body

The present invention relates to a technique for making an extension tape for TAB wire bonding or the like of a solar cell.

Since the prior art, an elongate belt for elongating various electronic parts and the like has been known.

Such an adhesive tape is formed in a form of a narrow strip formed on an elongated release sheet and wound up in a roll form on a turntable.

Further, at the manufacturing site, the belt is taken out from the turntable and used, and if the belt is used up, the production line is temporarily stopped and replaced with the turntable.

However, if the length of the belt is short, the production line must be stopped every time the turntable is replaced, so that the production efficiency is lowered.

Therefore, in recent years, it has been desired to make the length of the endless belt that can be wound around one turntable as long as possible, that is, "longer".

However, in order to increase the length of the adhesive tape, it is necessary to take measures such as increasing the length of the roll for applying the adhesive, or winding up the coating mechanism, and increasing the size of the winding portion, and the large lengthening exists. The limitation is that it is necessary to uniformly control the coating thickness of the subsequent tape and the like.

Further, as a prior art document related to the present invention, for example, the following is shown.

[Advanced technical literature] [Patent Literature]

[Patent Document 1] Japanese Patent Laid-Open Publication No. 2011-52061

The present invention has been made in view of the above-described technical problems, and an object thereof is to provide a technique for achieving a large enlargement of a subsequent belt without changing a conventional coating mechanism of a reel or an adhesive.

In order to achieve the above object, the present invention provides an adhesive tape structure in which a plurality of subsequent tapes are joined via a connecting tape, and the adhesive tape is sequentially provided with an adhesive layer and a release film on the base film. The adhesive tape layer and the release film are sequentially provided on the connecting substrate; and the adhesive tape structure is provided with a predetermined interval between the end portion of the adhesive tape and the end portion of the connecting tape. The end portion of the base film of the adhesive tape and the end portion of the connecting substrate of the connecting tape are connected by a substrate-side adhesive member, and the release film of the adhesive tape and the adhesive tape of the adhesive tape can be used. The method of integrally peeling the belt in the longitudinal direction, and the end portion of the peeling film and the end portion of the release film are separated by the peeling side joining member, and the type of the base resin of the adhesive layer of the base material side connecting member and the peeling The type of the base resin of the adhesive layer of the side-by-side member is different.

Moreover, the present invention is an adhesive tape structure in which a plurality of subsequent tapes are connected via a connecting tape, and the adhesive tape is sequentially provided with an adhesive layer and a release film on the base film, and the adhesive tape is attached to the adhesive tape. An adhesive layer and a release film are sequentially disposed on the connecting substrate; In a state in which a predetermined interval is formed between the end portion of the tape and the end portion of the connecting tape, the end portion of the base film of the adhesive tape and the end portion of the connecting substrate of the connecting tape are followed by the substrate side. In addition, the peeling film of the above-mentioned adhesive tape and the peeling film of the said connecting tape can be peeled in the longitudinal direction of the tape, and the edge part of the peeling film and the edge part of the peeling film are peeled off. Next, the thickness of the adhesive layer of the substrate-side member is different from the thickness of the adhesive layer of the peel-side member.

In the present invention, it is also effective when the thickness of the adhesive layer of the substrate-side member is different from the thickness of the adhesive layer of the peel-side member.

In the present invention, it is also effective when the thickness of the adhesive layer of the peeling-side member is thinner than the thickness of the adhesive layer of the substrate-side member.

In the present invention, it is also effective when the ratio of the thickness of the adhesive layer of the peeling-side member to the thickness of the adhesive layer of the substrate-side adhesive member is less than 50/100.

In the present invention, it is also effective when the connecting base material of the connecting belt is made of a non-translucent material.

In another aspect, the present invention is an adhesive tape holder which is wound around a turntable member in a traverse winding manner, the turntable member having a width larger than the adhesive tape structure. The flange spacing of the bandwidth.

The adhesive tape structure system of the present invention is configured such that the end portion of the base film of the tape and the end portion of the connecting substrate of the bonding tape are followed by the substrate-side member, and the film is peeled off and peeled off. The film can be integrally peeled off, and the end portion of the release film of the adhesive tape and the end portion of the release film of the adhesive tape are followed by the peeling side adhesive member; The basic structure and function of the belt are the same as those of the conventional belt, and the adhesive can be continuously attached to the adherend using the conventional attaching device.

As a result, according to the present invention, it is possible to achieve a large enlargement of the subsequent belt without changing the coating mechanism of the existing reel or the adhesive.

Further, according to the present invention, since the type of the base resin of the adhesive layer of the substrate-side member is different from the type of the base resin of the adhesive layer of the peel-side member, the release film self-adhesive agent is applied to the end portion of the adhesive tape. When the layer is peeled off and the release film is peeled off from the adhesive layer at the end of the tape, even if the adhesive layer of the peeling side contact member contacts the adhesive layer of the substrate side adhesive member, the adhesive can be prevented from following each other. Therefore, the release film and the release film can be smoothly peeled off.

In the present invention, when the thickness of the adhesive layer of the substrate-side member is different from the thickness of the adhesive layer of the peeling-side member, for example, the thickness of the adhesive layer formed as the peeling-side member is thinner than the substrate-side member. When the thickness of the adhesive layer is formed, the thickness of the adhesive layer of the peeling-side adhesive member is formed to be equivalent to the thickness of the adhesive layer of the substrate-side adhesive member, and the adhesion between the adhesive layers can be reduced. When the peeling film is peeled off from the adhesive layer at the end of the connecting tape, and the peeling film is peeled off from the adhesive layer at the end of the tape, even if the adhesive layer of the substrate-side adhesive member contacts the peeling-side member The adhesive layer can also reliably prevent the adhesive layers from coming to each other, so that the release film can be smoothly peeled off.

In this case, if the ratio of the thickness of the adhesive layer constituting the peeling-side member to the thickness of the adhesive layer of the substrate-side adhesive member is less than 50/100, the adhesive layer of the peeling-side member can be surely prevented from contacting the base. Since the material is adhered to the adhesive layer of the member, the release film and the release film can be peeled off more smoothly.

In the present invention, when the connecting substrate of the connecting tape is made of a non-translucent material, the connecting substrate can be detected by the photosensor, whereby the portion of the connecting tape can be skipped and the adherend can be continuously Attach an adhesive.

In another aspect, in the adhesive tape container of the present invention, the adhesive tape structure system is wound around the turntable in a rewinding manner, the turntable having a flange interval wider than a bandwidth of the adhesive tape structure, according to the present invention Then, with the container, the extremely long end belt structure can be wound and smoothly extracted. Therefore, in the attaching step of the belt, the turntable does not need to be frequently replaced, and the production efficiency can be greatly improved.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

Fig. 1 (a) is a side view showing a basic configuration of an embodiment of an adhesive tape structure according to the present invention, and Fig. 1 (b) is a side view showing a main portion of the same tape structure.

The subsequent belt structure 1 of the present embodiment is a series of elongated persons in which a plurality of subsequent belts 2 are linearly connected via the connecting belt 3, respectively.

Here, the tape 2 has the same configuration, and is a so-called three-layer structure in which the adhesive layer 21 and the release film 22 are sequentially provided on the entire surface of the base film 20.

On the other hand, the connection tape 3 has the same configuration, and is a so-called three-layer structure in which the adhesive layer 31 and the release film 32 are sequentially provided on the entire surface of the connection substrate 30.

In the present embodiment, the connecting belt 3 is configured to have a shorter length than the succeeding belt 2. Furthermore, the length of each of the subsequent belts 2 and the length of each of the connecting belts 3 may be the same or different.

Then, the upper surface of the end portion of the base film 20 of the tape 2 (the surface opposite to the adhesive layer 21) and the upper surface of the end portion of the bonding substrate 30 of the bonding tape 3 (the opposite side of the adhesive layer 31) ) are respectively joined by the substrate-side member 41.

Further, the upper surface of the end portion of the peeling film 22 of the tape 2 (the surface opposite to the adhesive layer 21) and the upper surface of the end portion of the release film 32 of the joining tape 3 (the opposite side of the adhesive layer 31) The surface is followed by peeling off the side-contact member 42.

Next, the base film 20 of the belt 2 can be made of, for example, PET.

The thickness of the base film 20 is not particularly limited, but a thickness of 10 to 100 μm can be preferably used from the viewpoint of ensuring the strength of the material and not increasing the winding diameter.

Further, the width of the base film 20 is not particularly limited, but it is surely covered by each From the viewpoint of electronic components, a width of 200 to 5000 μm can be preferably used.

Further, the upper surface of the base film 20 may be subjected to a peeling treatment using, for example, a polyoxymethylene resin.

Next, the adhesive layer 21 of the tape 2 can be a resin used in a usual adhesive for the tape, in particular, a thermosetting resin (for example, an epoxy resin, a phenoxy resin, a urethane resin, or the like).

The thickness of the adhesive layer 21 is not particularly limited. However, from the viewpoint of reliably connecting terminals having uneven heights of various electronic components, the thickness thereof is preferably set to 10 to 100 μm.

Next, the release film 22 of the tape 2 protects the adhesive layer 21 and is peeled off when used.

As the release film 22, for example, a member made of PET can be used.

In the present invention, the thickness of the release film 22 is not particularly limited, but is preferably set to 10 to 100 μm from the viewpoint of ensuring the strength of the material and not increasing the winding diameter.

In summary, the preferred thickness of the adhesive tape 2 is 30 to 300 μm.

On the other hand, the length of the above-mentioned adhesive tape 2 is not particularly limited, but the length can be preferably used in consideration of the number of times of skipping when using the tape structure 1 and the maximum coating length of the coating device of the tape 2 For 50~1000m.

On the other hand, as the connecting base material 30 of the connecting tape 3, a non-translucent material which can be detected by a photo sensor can be used.

As such a connecting base material 30, for example, a filler (filler) in which black is dispersed in a resin composed of PET can be used.

The thickness of the connecting base material 30 is not particularly limited, but it can be preferably made from the viewpoint of ensuring a thickness equivalent to the base film 20 of the tape 2 to prevent a step difference during winding. Use a thickness of 10 ~ 100μm.

On the other hand, the width of the connecting base material 30 is not particularly limited, but from the viewpoint of smoothly winding, extracting, and traversing the adhesive tape structure 1, it is preferable to set the base film 20 with the tape 2 The width is equal.

The adhesive layer 31 of the connecting tape 3 is used to smoothly peel off the peeling film 32 of the connecting tape 3.

That is, as described below, the release film 32 of the connection tape 3 is peeled off together with the release film 22 of the tape 2, but there is no adhesion between the release film 32 of the connection tape 3 and the connection substrate 30. When the material is peeled off, the speed of the peeling film 32 is temporarily increased, and thus the conveying speed of the production line may vary.

Further, when there is no adhesive property between the release film 32 of the connecting tape 3 and the connecting base material 30, a serpentine occurs when the slit is formed when the tape structure 1 is subsequently produced. The belt may wrinkle or the belt may break.

The adhesive layer 31 of the present invention is used to prevent the above-mentioned problems.

In view of the above, it is preferable that the peeling force of the adhesive layer 31 and the release film 32 of the connecting tape 3 is 0.2 times or more of the peeling force of the adhesive layer 21 and the peeling film 22 of the tape 2 Less than the following.

Here, the "peeling force" can be measured based on JIS K 6854-3, using TENSILON manufactured by OLIENTEC as a tensile tester, and performing a T-peel test at a peeling speed of 300 mm/min.

If the peeling force of the adhesive layer 31 of the joining tape 3 and the peeling film 32 is less than 0.2 times the peeling force of the adhesive layer 21 of the tape 2 and the peeling film 22, peeling film may be peeled off. The speed of 32 o'clock rises to cause a deviation in the conveying speed of the production line, or the belt may wrinkle or break the belt due to the meandering during the slitting.

On the other hand, if the peeling force of the adhesive layer 31 of the joining tape 3 and the peeling film 32 is more than 2.0 times of the peeling force of the adhesive layer 21 and the peeling film 22 of the tape 2, the adhesive tape of the adhesive tape 3 may not be adhered. The agent layer 31 smoothly peels off the release film 32.

As long as the above conditions are satisfied, the adhesive layer 31 of the bonding tape 3 may be any resin which has the same or different composition as the adhesive layer 21 of the tape 2 subsequent thereto. Further, as the resin having a composition different from that of the adhesive layer 21 of the tape 2, for example, a polyoxynenoid resin is exemplified.

Further, in order to satisfy the above conditions, the thickness of the adhesive layer 31 can be set to 10 to 100 μm.

On the other hand, the adhesive layer 31 of the connecting tape 3 is not originally transferred to the portion to be skipped by the adherend, and therefore, the non-hardening resin or hardened portion is used only for the portion of the adhesive layer 31. Resin for improved storage stability.

Further, when the adhesive layer 21 of the tape 2 is used, for example, a high-priced filler or the like, by forming the adhesive layer 31 with a relatively low-cost material, the manufacturing cost can be suppressed.

In the present invention, the adhesive layer 31 may be formed of a light transmissive material.

That is, by connecting the connecting substrate 30 of the connecting tape 3 with the non-translucent material as described above, the connecting substrate 30 of the connecting tape 3 can be detected by the photo sensor, but when the photo sensor is attached When the side of the agent layer 31 is present, the adhesive layer 31 may block light so that the connection substrate 30 cannot be detected.

Therefore, in this case, the adhesive layer 31 of the connection tape 3 is formed by the light-transmitting material, and the connection substrate 30 can be detected by the photosensor via the adhesive layer 31.

In the present invention, the adhesive layer 31 is preferably configured to be visible light from the viewpoint of reliably detecting the connection base material 30 via the adhesive layer 31 by the photosensor. The transmittance (light transmittance) is 70% or more.

The release film 32 of the connection tape 3 protects the adhesive layer 31 and is peeled off during use.

As the release film 32, for example, a member made of PET can be used.

In the present invention, the thickness of the release film 32 is not particularly limited, but it is preferably set to 10 from the viewpoint of ensuring a thickness equal to the thickness of the release film 22 of the tape 2 to prevent stepping during winding. 100 μm.

In summary, the preferred connecting strip 3 has a thickness of 30 to 300 μm, and preferably has a thickness equivalent to that of the succeeding strip 2.

On the other hand, the length of the above-mentioned connecting belt 3 is not particularly limited, but it is preferably set to 5 to 100 cm from the viewpoint of being able to be sensed by the photosensor and the line conveying speed is not lowered as much as possible.

The substrate-side member 41 is firmly adhered to the end portion of the base film 20 of the tape 2 and the end portion of the connection substrate 30 of the connection tape 3 by the adhesive layer 45 provided on the substrate 43.

On the other hand, the peeling side following member 42 is firmly adhered to the end portion of the peeling film 22 of the adhesive tape 2 and the end portion of the peeling film 32 of the connecting tape 3 by the adhesive layer 46 provided on the base 44.

Further, in the present invention, the end portion of the tape 2 and the end portion of the connecting tape 3 are provided with minute gaps as will be described later.

Further, the adhesive tape structure 1 of the present invention is obtained by connecting two or more of the above-described adhesive tapes 2 to each other by the above-mentioned connecting tape 3.

Fig. 2 is a view for explaining a step of thermocompression bonding a subsequent adhesive layer to a member to be bonded using the adhesive tape structure of the present embodiment, and Figs. 3(a) and (b) show the same steps. An explanatory view of a state in which the tape structure peels off the release film of the tape and the release film of the connection tape.

As shown in Fig. 2, in the present embodiment, the roll-up structure 1 is taken out from the roll 1A of the tape structure 1 wound on the turntable member 10, and the direction is switched by the take-up roll 11, and the above-mentioned tape 2 is removed by the peeling roller 12. The release film 22 is peeled off from the release film 32 of the connection tape 3.

Here, the release film 22 of the adhesive tape 2 is peeled off from the adhesive layer 21 by the operation of the peeling roller 12, but the release film 22 is separated from the release tape 32 of the adhesive tape 3 by the peeling side adhesive member 42. Then, the release film 32 of the peeling film 22 of the tape 2 and the connection tape 3 can be integrally peeled off (refer FIG. 3 (a), (b)).

Thereafter, the subsequent belt structure 1 is conveyed by the rollers 13 to 15, and the portion to be thermocompression bonded to the belt structure 1 is placed between the thermocompression joint 16 and the to-be-attached body 17, and the thermocompression joint 16 is operated at this position. On the other hand, the adhesive layer 21 of the tape 2 is transferred to the adherend 17 .

At this time, the non-transmissive connecting substrate 30 of the connecting tape 3 is detected by the photo sensor 5, and when the connecting substrate 30 has been detected, the connecting tape 3 is not located in the thermocompression bonding joint 16 and the adherend 17 The manner in which the adhesive layer 31 of the connecting tape 3 is transferred to the adherend 17 is controlled so as not to be transported by the tape structure 1 .

In the present invention, the adhesive layer 31 of the connecting tape 3 is formed of a light-transmitting material as described above, so that not only when the photosensor 5 is positioned on the side of the connecting substrate 30 of the connecting tape 3 but also in the light When the sensor 5 is located on the side of the adhesive layer 31 of the connection tape 3, the connection substrate 30 can be detected by the photo sensor 5 via the adhesive layer 31.

After the completion of the thermocompression bonding step, the belt structure 18 is conveyed by the guide roller 18, and the belt structure 19 is taken up by the winding device 19.

At this time, in the present embodiment, the adhesive layer 31 of the connecting tape 3 is not transferred to be attached. Since the body 17 is taken up by the winding device 19, the adhesive layer 31 remaining on the tape structure 1 is rotated next to the guide roller 18.

In the present invention, in order to prevent such a problem, the adhesive force of the adhesive layer 31 of the connecting tape 3 to the guide roller 18 can be adjusted to 200 gf/5 mm φ or less.

In this case, as the guide roller 18, a conductive roller made of polyoxyn resin may be used, or a surface of the guide roller 18 may be processed by using a resin such as polyether oxide resin or polytetrafluoroethylene resin. Guide rollers.

4(a) and 4(b) are explanatory views for explaining the problem of the present invention.

As described above, in the present invention, a slight gap is provided between the end portion of the tape 2 and the end portion of the connecting tape 3 (see Fig. 4(a)).

The reason for this is that it is considered that if the end portion of the adhesive tape 2 and the end portion of the connecting tape 3 are overlapped with each other and the peeling-side adhesive member 42 is subsequently joined, it is difficult to smoothly peel the adhesive film 22 of the adhesive tape 2 . The peeling film 32 of the connecting tape 3 is peeled off integrally; and the margin when the tape structure 1 is manufactured is considered.

Therefore, since a slight gap is formed between the end portion of the tape 2 and the end portion of the connecting tape 3, when the peeling film 32 is peeled off from the adhesive layer 31 at the end portion of the connecting tape 3, and then When the peeling film 22 is peeled off from the adhesive layer 21 at the end portion of the tape 2, the adhesive layer 46 of the peeling side adhesive member 42 comes into contact with the adhesive layer 45 of the substrate side adhesive member 41 to cause the adhesive layers 45 and 46 to follow each other. As a result, the release film 32 may not be peeled off (see FIG. 4(b)).

Therefore, in the present invention, the problem is solved as described below.

5(a) to 5(c), Fig. 6 and Fig. 7 are side views showing essential parts of an embodiment of the present invention.

In the embodiment shown in Figs. 5(a) to 5(c), the adhesive layer of the type of the base resin (for example, polyfluorinated resin) and the peeling side adhesive member 42 of the adhesive layer 45A of the substrate-side member 41 can be used. The type of the base resin of 46B is different (for example, an acrylic resin).

On the other hand, in the present invention, as described above, the thickness of the preferred adhesive tape 2 is 30 to 300 μm, and the thickness of the preferred bonding tape 3 is 30 to 300 μm.

Further, when the adhesive tape 2 and the peeling-side adhesive member 42 are used to connect the adhesive tape 2 to the adhesive tape 3, it is considered that the peeling film 22 of the adhesive tape 2 and the adhesive tape 3 are smoothly peeled off as described above. When the film 32 is integrally peeled off and the margin of the tape structure 1 is manufactured, it is more preferable to set the gap W between the end portion of the tape 2 and the end portion of the tape 3 to 10 to 1000 μm.

Further, in the present embodiment, as shown in FIG. 5(a), the thickness of the adhesive layer 45A of the substrate-side member 41 is equal to the thickness of the adhesive layer 46B of the peel-side member 42.

Under the above-described conditions, the substrate-side adhesive member 41 is not particularly limited. However, from the viewpoint of securing the necessary adhesive force, it is more preferable to use the adhesive layer 45A to have a thickness of 40 μm or more.

On the other hand, the peeling side adhesive member 42 is not particularly limited, but it is more preferable to use the adhesive layer 46B to have a thickness of 40 μm or more from the viewpoint of securing the necessary adhesive force.

In addition, the length of the substrate-side member 41 is not particularly limited, but it is preferable from the viewpoint of ensuring the adhesion between the adhesive tape 2 and the connecting tape 3 and the workability at the time of bonding as much as possible. Set to 1~10cm.

On the other hand, the length of the peeling-side member 42 is not particularly limited, but from the viewpoint of ensuring the adhesion between the adhesive tape 2 and the connecting tape 3 and the workability at the time of bonding as much as possible, The best setting is 1~10cm.

According to the embodiment having the above configuration, the substrate-side member 41 is The type of the base resin of the adhesive layer 45A is different from the type of the base resin of the adhesive layer 46B of the peeling side adhesive member 42. Therefore, for example, when the release film 32 is peeled off from the adhesive layer 31 at the end portion of the adhesive tape 3, Even if the adhesive layer 46B of the peeling side joining member 42 comes into contact with the adhesive layer 45A of the substrate side connecting member 41, the adhesive layers 45A, 46B can be prevented from coming to each other, so that the peeling film 32 can be smoothly peeled off (refer to FIG. 5(b) , (c)).

Further, when the release film 22 is peeled off from the adhesive layer 21 at the end portion of the adhesive tape 2, even if the adhesive layer 46B of the peeling side adhesive member 42 comes into contact with the adhesive layer 45A of the substrate side adhesive member 41, The adhesion layers 45A and 46B can be prevented from coming to each other, so that the release film 22 can be smoothly peeled off.

Fig. 6 shows another embodiment of the present invention.

As shown in Fig. 6, in the embodiment shown in Figs. 5(a) to 5(c), the thickness of the adhesive layer 45A of the substrate-side adhesive member 41 and the adhesive layer of the peel-side adhesive member 42 are as shown in Figs. 5(a) to 5(c). The thickness of 46B is different.

At this time, the thickness of the adhesive layer 46B of the peeling-side member 42 is thinner than the thickness of the adhesive layer 45A of the substrate-side member 41.

In the present invention, although the release film 32 of the connection tape 3 is peeled off from the adhesive layer 31 and the release film 22 of the adhesive tape 2 is peeled off from the adhesive layer 21, it is more sure. From the viewpoint of avoiding the adhesive layer 46B of the peeling side adhesive member 42 and then the adhesive layer 45A of the substrate side adhesive member 41, it is more preferable to set the thickness of the adhesive layer 46B of the peeling side adhesive member 42 to the substrate side. The ratio of the thickness of the adhesive layer 45A of the member 41 is then less than 50/100.

Specifically, in the above dimensional relationship, it is preferable to take into consideration the necessary adhesion force, The thickness of the adhesive layer 46B of the peeling side follower member 42 is set to 5 to 20 μm.

According to the present embodiment having the above-described configuration, the thickness of the adhesive layer 46B of the peeling-side member 42 is thinner than the thickness of the adhesive layer 45A of the substrate-side member 41, and the thickness of the adhesive layer 46B is formed to be the adhesive layer 45A. The adhesion between the adhesive layer 45A and the adhesive layer 46B can be reduced as compared with the case where the thickness is equivalent. Therefore, for example, when the peeling film 32 is peeled off from the adhesive layer 31 at the end portion of the adhesive tape 3, even if it is adhered The contact of the layer 45A with the adhesive layer 46B also reliably prevents the adhesive layers 45A, 46B from coming to each other, so that the release film 32 can be peeled off more smoothly.

Further, for the same reason, when the peeling film 22 is peeled off from the adhesive layer 21 at the end portion of the tape 2, the adhesive layer 46B of the peeling side adhesive member 42 comes into contact with the adhesive layer 45A of the substrate side adhesive member 41. The peeling film 22 can also be peeled off smoothly.

Fig. 7 shows another embodiment of the present invention.

In the present embodiment, the type of the base resin of the adhesive layer 45 of the base material side follower member 41 is the same as the type of the base resin of the adhesive layer 46 of the peeling side adhesive member 42, and the adhesive layer of the peeling side adhesive member 42 is further removed. The thickness of 46 is thinner than the thickness of the adhesive layer 45 of the substrate side follower member 41.

In this case, as the adhesive of the adhesive layer 45 of the substrate-side adhesive member 41 and the adhesive layer 46 of the peeling-side adhesive member 42, an adhesive containing an acrylic base resin can be preferably used.

In addition, in the same dimensional relationship as the above-described embodiment, the substrate-side adhesive member 41 is not particularly limited. However, from the viewpoint of securing the necessary adhesive force, it is more preferable to use the adhesive layer 45 to have a thickness of 40 μm or more. .
