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; and
an 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 × 10 7 to 10 × 10 7 Pa at 250°C, and
wherein a substance having 2 or more amino groups exists on the surface of the adhesion layer;
a coil containing the insulated wire; and
an electrical or electronic equipment using the coil.
