According to present embodiment, abandon the 5b of section by the volume that specified length is set in the terminal part 5c of anisotropic conductive band 5 side, when pulling out the anisotropic conductive band 5 that is wound on the reel parts, can suppress bond layer 8 with high level and peel off from base material 6.

Above, the utility model has been described preferred embodiment, but the utility model is not limited to above-mentioned embodiment.The utility model can carry out various distortion in the scope that does not break away from its main idea.

For example, in the above-described embodiment, illustration situation about towards the mode facing to the outside that is not formed with bond layer of volume core 1 side (inboard) and base material 6, anisotropic conductive band 5 being wound on core 1 according to bond layer 8, but the direction of anisotropic conductive band 5 can be also direction in contrast to this.Fig. 8 and adhesives reel 20 shown in Figure 9 according to base material 6 be not formed with bond layer be wound with anisotropic conductive band 5 facing to volume core 1 side (inboard) and bond layer 8 mode toward the outer side on volume core 1.

The anisotropic conductive band 5 of adhesives reel 20 also has the volume that does not use bond layer 8 from terminal part 5c in specified length and abandons the 5b of section, and the region division of abandoning between the 5b of section at the use 5a of section and volume has end mark EM.The terminal part 5c of anisotropic conductive band 5 namely rolls up more than the length (length L 3 of Figure 10) of abandoning the 5b of section is preferably 5m to the distance of end mark EM, 5 ~ 20m more preferably, and more preferably 5 ~ 15m, most preferably be 5 ~ 10m.By making length that volume abandons the 5b of section more than 5m, stick together in the time of can fully preventing from using adhesives reel 20, on the other hand, by making length that volume abandons the 5b of section below 20m, can suppress not use and the amount of discarded bond layer 8.Consider from same reason, the length that volume is abandoned the 5b of section is preferably under the state that is wound with anisotropic conductive band 5 on volume core 1 more than 10 circles, 10 ~ 30 circles more preferably, and more preferably 13 ~ 20 circles, most preferably be 15 ~ 20 circles.

According to adhesives reel 20, same with above-mentioned adhesives reel 10, by configuring end mark EM at assigned position, and rolling up coiling anisotropic conductive band 5 on core 1 according to base material 6 towards volume core 1 side and bond layer 8 mode toward the outer side, can further suppress reliably the generation of adhesion.About by the reason that anisotropic conductive band 5 reversing senses reeled obtain better effect and indefinite, but the inventor is presumed as follows.Namely can think, should use zone (the use 5a of section) at anisotropic conductive band 5, lining cement oozes out and adheres from the end face of bond layer 8 and is bonded on side plate 2, when pulling out anisotropic conductive band 5, base material 6 than more close volume core 1 side of bond layer 8 (inboard) can hold up bond layer 8, so the power of wanting to peel off between the bond layer 8 of the anisotropic conductive band 5 of pulling out and base material 6 is inoperative, and the impact that is bonded in the part on side plate 2 from adhesion is little, so can realize suppressing adhesion.

In addition, at this moment, bond layer 8 is exposed to the periphery of the folded body of volume of anisotropic conductive band 5, in order to make this part not by pollutions such as dusts, also can adopt as required following countermeasure.For example, for the last part of anisotropic conductive band 5 (part of reeling and finishing), remove in advance the bond layer 8 on base material 6 and remaining white part is set, fold on body by it is wound on, can prevent that bond layer 8 from exposing.Or also can be at base material 6, remaining white part be set, and but prepare other band (but the same material of illustration and base material), it is attached at the end of base material 6 and is wound on and folds on body.Except above-mentioned, also can preserve the pollution of avoiding from external environment condition by adhesives reel 20 being put into bag.
