1. An electric cable, including:
- a conductor being made of wires a diameter of each of which is from 0.15 to 0.5 mm and having a cross-sectional area of 20 mm2 or more; and
an insulating resin including a flame retardant and covering an outer periphery of the conductor,wherein a ratio of a diameter of the electric cable to a diameter of the conductor is from 1.15 to 1.40, andwherein a secant modulus of the insulating resin is from 10 to 50 MPa.

Abstract
An electric cable for improving flexibility of an insulating resin portion of the electric cable expressed by a secant modulus value is provided. In an electric cable 10a in which an outer periphery of a conductor 11 made of wires with diameters from 0.15 to 0.5 mm and having a cross-sectional area of 20 mm2 or more is covered with an insulating resin 12 including a flame retardant, a ratio of an electric cable diameter to a conductor diameter is from 1.15 to 1.40, and a secant modulus of the insulating resin 12 is from 10 to 50 MPa.
