Original Abstract Submitted
a board laminate includes a plurality of strip-shaped flexible circuit boards bent into a cylindrical shape and stacked in a radial direction of the cylinder. each of a plurality of the flexible circuit boards includes a continuous wire formed by a plurality of partial wires formed on each of two main surfaces of a strip-shaped insulating sheet and formed on each main surface are alternately connected in cascade via vias. the continuous wire has crossings in a chain-like shape without electrical continuity with each other in a projection plan view seen in a normal direction of the main surface of the insulating sheet, to form a plurality of annular portions. in a plurality of the flexible circuit boards, the flexible circuit board has a longer length of the insulating sheet as the flexible circuit board is placed further from a central axis of the cylinder.
