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.
