PROBLEM TO BE SOLVED: To provide a method of manufacturing a preformed coil that has superior productivity and stable quality, and can reduce manufacturing costs, and to provide the preformed coil. SOLUTION: In the method of manufacturing the preformed coil by winding a rectangular copper wire, the rectangular copper wire is wound ovally for forming a row of wiring before another row of wiring is continuously formed at a side adjacent to the row of wiring, and both the rows of wiring are changed for manufacturing the preformed coil, thus manufacturing the preformed coil without performing any connection work inside the preformed coil and eliminating the step rise section of the rectangular copper wire.
