An excellent insulated wire having a high partial discharge start voltage and wear resistance, a method for producing the same, and an electrical device are provided. SOLUTION: A conductor 1, a foamed insulating layer 2 containing a thermosetting resin having air bubbles, which is directly or indirectly coated on the outer peripheral surface of the conductor 1, and a crystalline resin outside the foamed insulating layer 2. In the case of a thermoplastic resin or an amorphous resin having a melting point of 240 ° C. or higher and a storage elastic modulus at 25 ° C. of 1 GPa or higher, the glass transition temperature is 240 ° C. or higher and the storage elastic modulus at 25 ° C. An insulating wire having an outer insulating layer 3 containing a thermoplastic resin having a GPa of 1 GPa or more, a manufacturing method thereof, and an electric device. [Selection] Figure 1 |
