摘要： An electrically insulated wire includes a rectangular conductor having a substantially rectangular cross section with corners shaped in a circular arc, and an electrical insulating coating formed by heating an electrical insulating varnish applied to coat an outer periphery of the rectangular conductor. The electrical insulating coating includes a thickest portion and a thinnest portion in a peripheral direction thereof. The rectangular conductor has a curvature radius of the corners of 0.6 mm or less and a ratio L2/L1 of 2.0 or less where L1 is a length of a short side in a width direction and L2 is a length of a long side in a longitudinal direction. The electrical insulating coating has a ratio d1/d2 of 1.3 or less where d1 is a coating thickness of the thickest portion and d2 is a coating thickness of the thinnest portion in the peripheral direction of the electrical insulating coating.

摘要： An insulated electrical wire is provided. The insulated electrical wire includes a conductor and an insulating film including pores. The insulating film at least includes a first insulating layer. The first insulating layer includes a first center region, a first inner side region, and a first outer side region. The first center region is a center region in the first insulating layer in a thickness direction and is formed of an insulating material and first pores that are the pores. The first pores are derived from a liquid thermally decomposable polymer. The first inner side region and the first outer side region are formed not to include the first pores.
