1. A stretchable cable, comprising:
an elastically deformable hollow insulation comprising a hollow portion continuous along a cable longitudinal direction; and
at least one electricity- or light-conducting wire-shaped body being provided in a spiral shape along the cable longitudinal direction and fixed to the hollow insulation to stretch and contract together with the hollow insulation,
wherein an entire part of the cable is elongated not less than 1.2 times when a tensile force is applied, and the cable returns to an original length of the cable when the tensile force is removed.
