The tacky-adhesive resin layer is not particularly limited, but conventionally known ones used in this field can be arbitrarily adopted. The facing position where the adhesive tape 4 is applied is preferably the edge of the cut portion 3 as shown in FIG. 1, but is not particularly limited. The width and length of the adhesive tape 4 are not particularly limited as long as the wire material 1 for lead wires to be attached can be adhesively attached so as to be peelable. In the present application, “adhesion with the adhesive tape 4 ” means that the lead wire material 1 or the lead wire 21 is temporarily fixed with the adhesive tape 4 .

When the wire material 1 for a lead wire is to be tightly wound in a single layer or wound at a constant pitch, it is preferable to provide the adhesive tape 4 so as to cover or cover the outer peripheral surface, and as shown in FIG. has the advantage that it can be made into a blind shape. Further, when the wire material 1 for lead wires is wound in multiple layers at a constant pitch, the adhesive tape 4 is preferably provided on and/or covering the outer peripheral surface, and may be provided at a location other than the facing position. It is possible to hold the lead wires 1 after cutting in such a way that they are not separated as much as possible. In the case of multi-layer winding, the adhesive tape 4 may be inserted and wound for each layer.
