Zusammenfassung:PROBLEM TO BE SOLVED: To provide a winding body capable of improving occupancy of winding per unit volume.SOLUTION: An electromagnetic coil is a winding body that is formed annular as a whole by laminating winding 20 of which the cross section is formed rectangular from an inner circumferential side to an outer circumferential side while winding it in a circumferential direction. In an inner circumferential part and an outer circumferential part of the winding body, a plurality of step parts 210, 211, 212, 220, 221 and 222 are provided of which the heights in a direction orthogonal with a central axis of the winding body are different for cross sections that pass the central axis. A transition part 24 is a portion of the winding 20 that connects portions of different heights in the step part 211 and extends obliquely with respect to the central axis. A transition part 25 is a portion of the winding 20 that connects portions of different heights in the step part 222 and extends obliquely with respect to the central axis. Each of the plurality of step parts 210, 211, 212, 220, 221 and 222 forms a step for one stage of the winding.SELECTED DRAWING: Figure 3 【課題】単位体積あたりに巻線が占める占有率を向上できる巻線体を提供する。【解決手段】電磁コイルは、矩形状断面をなす巻線20が周方向に巻回されて内周側から外周側に向けて積層されることにより全体として環状に形成される巻線体である。巻線体の内周部及び外周部には、巻線体の中心軸を通る断面について中心軸に直交する方向の高さがそれぞれ異なる複数の段差部210、211、212、220、221、222が設けられている。移行部24は、段差部211について高さが異なる部分間を繋げる巻線20の部分であって、中心軸に対して斜めに延びる。移行部25は、段差部222について高さが異なる部分間を繋げる巻線20の部分であって、中心軸に対して斜めに延びる。複数の段差部210、211、212、220、221、222のそれぞれは、巻線の一段分の段差をなす。【選択図】図3
