Title:
INSULATED WIRE
Document Type and Number:
WIPO Patent Application WO/2023/026591
Kind Code:
A1
Abstract:
This insulated wire comprises a linear conductor and an insulating layer that coats the outer peripheral surface of the conductor. The insulating layer contains, as residual solvents, a first solvent having a dielectric constant of at least 15 and a second solvent having a dielectric constant of less than 15. A first ratio, which is the ratio of the content of the second solvent to the total content of the first solvent and second solvent contained in the insulating layer, is at least 50 mass%. A second ratio, which is the ratio of the content of the second solvent to the total content of the first solvent and second solvent contained in the insulating layer after the insulated wire has been heat-treated by heating for 1 minute at 350°C, is higher than the first ratio.
