Abstract: A coil device 10 comprises a first bobbin 40 provided with a first winding part 45 at an outer circumference and a second bobbin 50 provided with a second winding part 55 at an outer circumference. A plurality of partition walls 46, separating portions of the wire 22 which are adjacent to each other along the scroll axis Z of the first wire 22 are formed on the first winding part 45 along the scroll axis at predetermined intervals. A section width w1 of each section 47, which is along the scroll axis Z, separated by the partition walls 46 is determined so that only one wire 22 can pass through. A height of the partition walls 46 is determined so that one or more of the wires 22 can pass through. At least one connecting groove 46a, connecting each section which are adjacent to each other, is formed on each partition wall 46.

Abstract translation: 线圈装置10包括在外周设置有第一绕组部分45的第一线轴40和在外周设置有第二绕线部分55的第二线轴50。 沿着第一线22的涡旋轴线Z彼此相邻的线22的分离部分的多个分隔壁46以预定间隔沿着滚动轴线形成在第一卷绕部分45上。 确定由分隔壁46分隔的沿着涡旋轴线Z的每个部分47的横截面宽度w1，使得只有一个导线22可以通过。 确定分隔壁46的高度，使得一根或多根电线22可以通过。 在每个分隔壁46上形成有至少一个连接槽46a，连接每个彼此相邻的部分。
