Abstract
An insulated electric wire includes a rectangular conductor and an insulation film disposed on the periphery of the rectangular conductor. The insulation film is characterized by: the provision of a resin containing an imide structure within a molecule; and a peak value of less than 1.0 for the loss tangent tan δ, which is represented by the ratio between the loss elastic modulus and the storage elastic modulus, as measured in the 50 DEG C. to 400 DEG C. range.
