Abstract

Selon l'invention, l'effet atténuation d'un filtre de bruit est préservé jusqu'à une haute fréquence, et simultanément il est possible d'empêcher le filtre de bruit d'atteindre une température élevée. Des motifs de terre (19a, 19b, 24a, 24b) de conducteurs de terre (19, 24) sont placés de manière à s'étirer côté extérieur d'un motif d'enroulement en des positions （２９）～（３２） s'opposant à des positions de bornes d'entrée et sortie (3, 6, 14, 18) d'un motif d'enroulement d'un conducteur d'enroulement (100), et des fentes (２０）～（２３） et （２５）～（２８）qui partagent une section disposée autour d'un noyau de corps magnétique (400), sont agencées sur les motifs de terre (19a, 19b, 24a, 24b) des conducteurs de terre.
