PROBLEM TO BE SOLVED: To provide a coil of an electric device in which varnish penetrates into spaces between conducting wires of the coil of the electric device and thereby improves insulation characteristics and heat radiation characteristics, and to provide a coil manufacturing method of the electronic device.SOLUTION: In a coil 50 of an electric device, a conducting wire 2 wound around an iron core 1 in a column direction L and a layer direction N multiple times and a fiber bundle 3 formed by bundling multiple raw fibers 3a are provided at the iron core 1. The fiber bundle 3 fills spaces S formed between portions of the conducting wire 2, and spaces between the raw fibers 3a and spaces between the conducting wires 2 are impregnated with varnish 4. |
