A distance between the flat surfaces opposite to each other is h. Four endpoints connecting the opposite flat surfaces and the corner regions and the opposite flat surfaces surround and form a middle region. The middle region has a rectangular structure. A length of the middle region in a winding direction is d, and a maximum thickness of each of the corner regions in the winding direction is a, where 0.015≤2a/dh≤0.1.
