Abstract: A method of manufacturing a coil and attaching the coil to contact points of an electric circuit. One end of a winding filament is brought in a stretched state to a first position in a winding machine, the filament is wound to provide a coil, and the filament after the finished coil is stretched to a second position and cut. The first and second positions are located inwardly of the coil. A circuit fixture carrying an electric circuit at a third position, which corresponds to the first and second positions inwardly of the coil, is caused to collect the wound coil, and the filament ends are welded together at the contact points on the electric circuit. The ends of the winding filament are held firmly at the first and second positions, respectively, by means of a hole with subpressure in the winding machine, and at the third position by means of a hole with subpressure in the circuit fixture.
