An insulated wire (10) of the present invention includes: a copper alloy conductor (1); and at least one resin layer (4) directly or indirectly coated on an outer peripheral face of the copper alloy conductor (1). The copper alloy conductor (1) 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 texture where when a crystal orientation distribution function obtained from texture analysis by EBSD is expressed using Euler angles (ϕ1, Φ, and ϕ2), 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.
