Abstract: Provided is an insulated wire that can inhibit a decrease in adhesion between an insulation film including pores and a conductor. The insulated wire comprises a conductor having a long shape, and an insulation film including multiple pores and covering the conductor. The opening area ratio SR measured by a method below is 20% or less. The method of measuring the opening area ratio SR:peeling the insulation film from the conductor; obtaining a SEM image showing an interface on a conductor side in the insulation film peeled; calculating an area S1 of an observation region that is at least a part of the SEM image; and an area S2 of portions where the multiple pores are open in the observation region; and calculating the opening area ratio SR by the following Formula (1).


SR=(S2/S1)×100.  Formula (1)
