Abstract
A coil structure includes a first winding portion and a second winding portion disposed so as to overlap each other with winding axes substantially parallel to each other. The first winding portion and the second winding portion have regions overlapping each other when viewed from a winding axis direction. The second winding portion has a rising portion extending in a cross section perpendicular to a direction of a current flowing through a conductor constituting the winding portion with a directional component away from the first winding portion included.

A coil structure comprising a first winding portion and a second winding portion disposed so as to overlap each other with winding axes substantially parallel to each other, wherein
- the first winding portion and the second winding portion have regions overlapping each other when viewed from a winding axis direction, and
- the second winding portion has a rising portion that extends perpendicular to or at an angle with respect to the first winding portion,
- wherein the first winding portion has a base facing portion that faces the second winding portion and extends between side end portions of the first winding portion in a direction perpendicular to the winding axis of the first winding portion, with a width in the direction perpendicular to the winding axis of the first winding portion that is greater than a height of the first winding portion in a direction parallel to the winding axis, and
- wherein, when the coil structure is viewed from the winding axis direction, for the regions overlapping each other when viewed from the winding axis direction, the rising portion is located within outer edges of the first winding portion, and
- the rising portion extends away from the first winding portion with respect to a portion of the second winding portion that faces the first winding portion.
