Summary:In the present invention, an insulating coating (26) in a ring section (21) of a secondary coil unit (20) is configured by compositing strip-shaped insulating paper (31, 32) wound so as to be staggered in the circumferential direction so as to reciprocate on the inner diameter side and the outer diameter side of a ring main body section (25a) of an inner conductive case (25), and sheet-shaped insulating paper (33) that is wound so as to reciprocate on the inner diameter side and the outer diameter side of the ring main body section (25a) of the inner conductive case (25). The sheet-shaped insulation paper 33 can be installed on the outer diameter side of the ring body part 25a in a bias manner. 本发明中，二次线圈单元20的环部21中的绝缘包覆体26是以复合的方式使用带状绝缘纸31、32和片状绝缘纸33来构成，所述带状绝缘纸31、32以在内侧的导电壳25的环本体部25a的内径侧和外径侧往复的方式沿周向错开并缠绕，所述片状绝缘纸33能够偏倚性地安装于环本体部25a的外径侧。
