Abstract
A self-supporting cable includes a main cable constructed by covering a cable core with an inner cover layer and installing one or more strength members inside the inner cover layer such that they lie on a plane passing through the central axis thereof; a support member; and an outer cover layer formed so as to cover the main cable and the support member while they are arranged in parallel. A support member portion including the support member and a part of the outer cover layer and a main cable portion including the main cable and a part of the outer cover layer are connected by connecting portions, which are also a part of the outer cover layer, in the longitudinal direction thereof. The main cable portion is made longer than the support member portion so that there is an allowance in the length thereof.
