PROBLEM TO BE SOLVED: To provide an inexpensive winding-like connecting member which does not transfer to the confronting separator base and can attain very stable release of the separator base. SOLUTION: There is provided a winding consisting of a separator base 5 made of a material having a significant difference between the surface tensions on its face and back and an adhesive layer 5 formed on either of its surfaces, wherein the separator base 5 comprises at least two layers, and the surface tension on the surface on which the adhesive layer is formed is larger than that on the back surface. There are also provided a winding as described above, wherein the adhesive layer 6 contains conductive microparticles having a mean particle diameter of 1-20μm and a winding as described above, wherein its width is 3 mm or below.
