The first sheet is wound on the plural cables so that a non-self-adhesive layer formed on a second surface, opposite to the first surface, of the first sheet is located inside. The second sheet includes a base sheet and a self-adhesive layer formed on a whole of only first surface of the base sheet. The second sheet is wound on the first sheet so that the self-adhesive layer of the first surface of the second sheet is located inside.
