摘要

A conductor (1) is wound around a plurality of times so as to form an annular shape, and a plurality of conductors are laminated.Coyle end part72) the outer shape is stacked in a staircase in the stacking directionThe storage part (6) is laminated in the form of a straight line in the stacking direction (H);An intermediate (50) of unit Coyle (5) is formedBoth Coyle end72) the Coyle end portion (71) protruded from the housing part (6) in the axial direction (y) in the layer in which the axial (y) length between the two is large72)In the direction away from the position of the housing part (6) in the stacking direction (H) as compared with the previous stateCoyle end part (71) of intermediate (50)72) bendCoyle end partIn step 72, the axial direction (y) of the annular inner side of the ring is formed so as to be aligned with each layer, thereby forming unit Coyle (5).
