To positively align and wind wire of even different outer diameters by providing plural rows of wire winding grooves at a sheet between wire aligned layers, and winding this sheet on the outer periphery of a bobbin drum part of a bobbin.
A sheet 4 between wire aligned layers wound on the outer periphery of a bobbin collar part 2 of an aligning-winding bobbin l is prepared determining a wire winding groove row, the depth of the groove row, winding pitch and a wire-to-wire gap in conformity to the outer diameter of wire to be wound. The sheet 4 is wound on one aligned-wound layer of the wire, and a second layer of wire is aligned-wound on the layer of the sheet 4. Insert- winding of the sheet 4 between the wire aligned layers and aligning-winding of the wire are thus repeated to align and wind the wire neatly without winding collapse or the like.
