Insulated wire, coil, and electrical or electronic equipment

An insulated wire, having:a single conductor or multiple conductors;an insulating layer on the outer periphery of the single conductor or each of the multiple conductors; andan adhesion layer on the outer periphery of the insulating layer, wherein the thickness of the adhesion layer is 2 to 200 µm,wherein a resin constituting the adhesion layer does not have a melting point, wherein the resin constituting the adhesion layer has a tensile modulus of 0.6 × 10to 10 × 10Pa at 250°C, andwherein a substance having 2 or more amino groups exists on the surface of the adhesion layer;a coil containing the insulated wire; andan electrical or electronic equipment using the coil.
