A method of manufacturing a transformer coil including a conductive winding enclosed in a resin using a mold including two tubular inner mold parts and one outer mold part with a length at least as long as the inner mold parts, the method includes the steps of winding a first conductor around a first inner mold part, winding a second conductor around a second inner mold part, joining one end of the first inner mold part to one end of the second inner mold part forming a sealed joint, connecting electrically the first and second conductors forming one winding, arranging the joined inner mold parts with the winding in the outer mold part, enclosing the winding between the inner and outer mold parts, filling resin into the space enclosed between the mold parts, letting the resin cure, and removing the mold parts.
