A self-bonding insulated wire having a bonding layer on an insulated wire, the bonding layer including a crystalline copolyamide having a melting point within the range of 105 to 150° C. and a relative viscosity of 1.4 to 1.6 measured at 25° C. with respect to a 0.5% by weight m-cresol solution thereof, and optionally at least one member selected from the group of a high-melting nylon having a melting point within the range of 200 to 300° C. and an antioxidant. The bonding layer can be formed from a coating having an increased resin concentration and the residual solvent content of the bonding layer is small. The self-bonding insulated wire and self-bonding litz wire composed thereof provide deflecting coils having a decreased strain, good adhesive property and good heat resistance.
