Abstract

L'invention porte sur un fil électrique isolé possédant une excellente propriété à haute fréquence et une excellente propriété d'isolation. Le fil électrique isolé est constitué d'un fil assemblé (11) ayant une section circulaire formée par assemblage de sept fils émaillés (4) ayant une section non circulaire; et d'un premier revêtement isolant (1) formé par enroulement d'un ruban isolant autour de la périphérie extérieure du fil assemblé (11) afin de lier le fil assemblé (11). Le fil électrique isolé peut réduire les pertes à haute fréquence par comparaison à un fil unique ayant la même aire de section, et peut réduire son diamètre extérieur par comparaison à un fil de Litz ayant la même aire de section. En outre, la force de liaison pour le fil assemblé peut être facilement maintenue par enroulement du ruban isolant autour du fil assemblé, sans torsader le fil assemblé. En conséquence, la variation de la forme extérieure du fil assemblé peut être réduite, et la propriété d'isolation peut être améliorée.
