Abstract
A method for producing a coil, in particular an ignition coil for a motor vehicle, in which a primary winding is wound onto a winding mandrel. Then the winding mandrel is introduced into a housing of the coil and the winding mandrel then is removed from the housing, the primary winding remaining inside the housing. Finally, additional components of the coil, in particular a secondary coil shell onto which a secondary winding has been wound, are introduced into the housing, so that the secondary winding is concentrically disposed within the primary winding while dispensing with a separate primary coil shell. The method allows a design of the coil that is more compact in diameter.
