         5 . A method of winding a tape, comprising the steps of:
 (a) providing an object, wherein the object is an adhesive tape provided with an adhesive layer or a sticky tape provided with a sticky layer; and   (b) winding the object up around a reel, wherein the reel comprises
 i. a columnar wind-up unit; and 
 ii. a pair of side plates arranged so that the wind-up unit is disposed between the side plates, and an inner surface of one or both of the side plates is provided with a peripheral projection extending in a circumference direction, 
   wherein during winding the object is slightly tilted and a side surface of the object is guided by a peripheral part of the side plate.   
     
     
         6 . The method of winding a tape according to  claim 1 , wherein the object is the adhesive tape provided with the adhesive layer. 
     
     
         7 . The method of winding a tape according to  claim 2 , wherein the adhesive tape is provided by cutting an isotropic conductive film into a narrow tape, wherein the isotropic conductive film is obtained by incorporating conductive particles into an adhesive layer formed on a substrate. 
     
     
         8 . The method of winding a tape according to  claim 1 , wherein at least a part of the peripheral projection that is in contact with the object has a circular shape, wherein the part of the peripheral projection that is in contact with the object when the object is wound guides the side surface of the object at a periphery of the side plates. 
     
     
         9 . The method of winding a tape according to  claim 1 , wherein a height of the peripheral projection is 0.05 mm to 1.00 mm. 
     
     
         10 . The method of winding a tape according to  claim 1 , wherein a width of the peripheral projection is 0.5 mm to 20.0 mm.
