Abstract
A small-diameter insulated wire has a small diameter and high bending resistance. In a small-diameter insulated wire having a conductor and an insulating layer covering the conductor, a cross-sectional area of the conductor is 0.08 mm2 or more and 0.4 mm2 or less, the conductor is a copper alloy having a breaking strength of 815 MPa or more, a breaking strength of the insulating layer is 36.5 MPa or more, a thickness of the insulating layer is 0.1 mm or more and 0.2 mm or less, and a conductor pullout force for drawing the conductor from the small-diameter insulated wire is 9 N/30 mm or less.
