Abstract: A coil includes: a strand-wound body configured with stacked n turns of a wound strand that is made of a conductor and has a quadrangular cross-section, where n is a natural number; and an insulating resin covering a surface of the strand-wound body. An i-th turn, where i is an integer and 1≤i≤n, has a quadrangular ring shape having four side portions, and in the i-th turn, the insulating resin covers a surface of each of the four side portions. In the first to n-th turns, the insulating resin is continuously and integrally formed.
