Abstract:
A structure has: 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. That is, 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. At least one of the pair of first support surfaces has a projecting part that protrudes toward the conducting wire. The top part of the projecting part is positioned farther to the inside than both end parts of the short side direction of the first support surface.
