Document Type and Number:
WIPO Patent Application WO/2019/026422
Kind Code:
A1
Abstract:
A structure having: a tubular support surface extending in the magnetic core direction of a coil; and a coil constituted by a conducting wire wound on the support surface. The support surface is a quadrilateral shape in which the long sides and the short sides are alternately aligned as seen in the magnetic core direction. The support surface has a pair of first support surfaces corresponding to the short sides, and a pair of second support surfaces corresponding to the long sides. The conducting wire is wound in a winding direction around the support surface from a winding start part in contact with the support surface toward a winding end part set at a distance farther from the support surface than the winding start part. At least one of the pair of first support surfaces is an inclined surface that intersects at an obtuse angle with respect to the second support surface positioned to the downstream side in the winding direction.
