An insulated wire including a conductor having a diameter of 1 mm or less and a foamed-polyolefin insulation layer of 2 mm or less in thickness, the insulation layer having an equivalent dielectric constant of less than 1.45 and a sidewall-pressure deformation of 20% or less. The polyolefin used is made of a mixture having an ionomer/polypropylene weight ratio between 20:80 and 80:20. The insulated wire may have, in addition to the foamed insulation layer, an outer solid insulation layer mainly consisting of polyolefin other than that used as the foamed insulation layer. In addition the insulated wire may have an inner solid insulation layer including polyethylene or acid-denaturated polyethylene.
