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.

摘要： In an insulated wire including a conductor formed into a long shape and an insulation film formed by stacking at least one insulating layer covering a circumference of the conductor, the insulating layer includes a porous region and a resin region. The porous region is formed of a resin and multiple voids, and the resin region is formed of the resin. In the insulating layer, a boundary surface is not provided between a first boundary surface located on a radially inner side and a second boundary surface located on a radially outer side, and the porous region and the resin region are arranged in this order from the first boundary surface toward the second boundary surface.

摘要： An insulated wire includes a conductor, and a polyimide insulation layer formed on an outer periphery of the conductor. The insulation layer includes a polyimide including a repeating unit represented by formula (1) and a repeating unit represented by formula (2). A first acid component in the repeating unit represented by the formula (1) and a second acid component in the repeating unit represented by the formula (2) are mixed in a molar ratio range of 85:15 to 40:60 as expressed by a molar ratio (the first acid component:the second acid component). R as a residue of a diamine component in the formulas (1) and (2) includes a residue of 4,4′-diaminodiphenyl ether and a residue of one selected from a group of diamines represented by the formulas (3) to (8). A storage elastic modulus of the polyimide at 325° C. is not less than 50 MPa.
