1. A coil comprising:
- a first winding which is composed of a single wire or a plurality of wires, and is wound about a winding shaft axis; and
a second winding which is composed of a single wire or a plurality of wires, and which is wound coaxially with the first winding so as to be in intimate contact with an outer circumferential portion of the first winding, whereinat least in the first winding among the first winding and the second winding, one side of a winding wire is wound from an inner circumferential side to an outer circumferential side, the other side of the winding wire is drawn forth from the inner circumferential side to the outer circumferential side, while crossing the one side of the winding wire, and a thickness in crossing portions of the one side of the winding wire and the other side of the winding wire in a direction of the winding shaft axis is equal to a thickness in other portions.

Abstract
A coil is formed by coaxially winding a second winding so as to be in intimate contact with an outer circumferential portion of a first winding wound about a winding shaft axis. In the first winding, one side of a winding wire is wound from an inner circumferential side to an outer circumferential side, the other side of the winding wire is drawn forth from the inner circumferential side to the outer circumferential side, while crossing the one side of the winding wire, and a thickness in a direction of the winding shaft axis in crossing portions of the one side of the winding wire and the other side of the winding wire is equal to a thickness in other portions.
