Abstract: An insulated wire includes: a copper alloy conductor; and at least one resin layer directly or indirectly coated on an outer peripheral face of the copper alloy conductor, in which the copper alloy conductor has a composition where a total content of metal components selected from Al, Be, Cd, Mg, Pb, Ni, P, Sn, and Cr is from 0.1 to 2.0 ppm and content of copper is 99.96 mass % or higher, and has a specific texture where an average orientation density in an area where φ2=0 degrees, φ1=0 degrees, and Φ=from 0 degrees to 90 degrees is from 3.0 to less than 35.0, and a maximum orientation density in an area where φ2=35 degrees, φ1=from 45 degrees to 55 degrees, and Φ=from 65 degrees to 80 degrees is from 1.0 to less than 30.0.

Abstract: Provided is an assembled wire 10 having a substantially rectangular cross section, and is formed by assembling a plurality of strands 7. Each strand 7 has a conductor portion 11 and a strand insulating layer 13 covering the conductor portion 11. The strand insulating layer 13 preferably contains at least one kind of resin in which 50% weight loss in Tg-DTA occurs at from 300° C. to 500° C. The strand insulating layer 13 contains particles. The particles are particles having volume resistivity of 1×106 Ω·cm or more, and, for example, inorganic substances such as silica, titania, alumina, aluminum nitride, magnesium oxide, silicon nitride, and silicon carbide; and resins such as silicone are applicable.
