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.
