An electronic wire and a cable which are excellent in bending resistance even when a diameter is small. The electronic wire has a conductor and a resin insulating layer coated on the conductor. The conductor is a double twisted wire in which twisted wires formed by twisting a plurality of wires are twisted, a diameter of the wire is 0.05 mm or more and 0.2 mm or less, a cross-sectional area of the conductor is 1.0 mm2 or more and 3.0 mm2 or less, a breaking elongation of the conductor is 10% or more and 17% or less, a tensile strength of the conductor is 200 MPa or more and 400 MPa or less, and the insulating layer is disposed to be in close contact with the conductor and has a solid structure.
