PROBLEM TO BE SOLVED: To provide an electric cable that has improved flexibility of an insulating resin portion of the electric cable expressed by a secant modulus.SOLUTION: There is provided an electric cable 10a in which an outer periphery of a conductor 11 made of plurality of wires having wire diameters of 0.15 mm or more and 0.5 mm or less is covered with an insulating resin 12 including a flame retardant, and in which a ratio of an electric cable diameter to a conductor diameter is 1.15 or more and 1.40 or less, and a secant modulus of the insulating resin 12 is 10 MPa or more and 50 MPa or less. Alternatively, there is also provided the electric cable in which the outer periphery of the conductor 11 is covered with an insulating resin 12' including a flame retardant, a shield conductor 13 is arranged in the outer periphery of the insulating resin 12', and the outer periphery of the shield conductor 13 is further covered with an insulating resin, and a ratio of an electric cable diameter to a conductor diameter is 1.40 or more and 1.77 or less, and a secant modulus of the insulating resin is 10 MPa or more and 50 MPa or less.SELECTED DRAWING: Figure 1 |
