PROBLEM TO BE SOLVED: To provide an electric cable that is effectively applied to a residence cable and other electric cables.SOLUTION: An electric cable has a spring material 5 capable of elastically deforming arranged between adjacent power supply core materials 3 adjacently to the core materials 3. Consequently, the electric cable 1 itself has elasticity, so when the electric cable 1 is applied to a residence cable of a contact-less type electric cable take-up device, the residence cable is prevented from buckling to bend during rotation of a take-up drum. The electric cable take-up device is thereby made compact. |
