Abstract
An insulated wire includes a conductor, and an insulation layer provided around the conductor. The insulation layer includes an inner layer located on a conductor side and an outer layer provided around the inner layer. The inner layer includes a halogen-free resin composition including a base polymer (A). The outer layer includes a cross-linked body obtained by cross-linking a halogen-free flame-retardant resin composition including a base polymer (B) and a halogen-free flame retardant. The base polymer (A) includes a thermoplastic resin (a1) having an aromatic ring in a backbone chain. The base polymer (B) includes a polyolefin component. A thickness of the inner layer is not less than 0.03 mm and not more than 70% of a thickness of the insulation layer.
