Abstract: A non-halogen insulating wire with excellent flame resistance as well as high mechanical characteristics (wear resistance) and electrical insulation characteristics is provided. A non-halogen two-layer insulating wire includes: a conductor; and an insulating layer having an insulating inner layer which covers an outer circumference of the conductor and an insulating outer layer which covers an outer circumference of the insulating inner layer The insulating inner layer is made of a first non-halogen resin composition which contains metal hydroxide and a base polymer (A) including polyolefin, and has a thickness of 20% to 58% of an entire thickness of the insulating layer. The insulating outer layer is made of a second non-halogen resin composition which contains metal hydroxide and a base polymer (B) including polyester resin and/or polyester elastomer resin.
