PROBLEM TO BE SOLVED: To manufacture a three-dimensional concentratedly wound coil, without using split bobbin and at the same time, to prevent a wound element wire from being damaged. SOLUTION: A concentratedly-wound coil winding device is provided with an integral rectangular bobbin 24, the rotating shaft of which can be moved in the axial direction and the direction perpendicular to the axial direction and a guide device 30 having four guide rollers 32-38, which guide an element wire 22 interlocked with the winding operation of the wire 22 around the bobbin 24. When the wire 22 is wound around the paired long or short sides of the bobbin 24, the second and third rollers 32 and 36 are moved to both ends of the bobbin 24 by widening the interval between the rollers 34 and 36 and thereafter, the bobbin 24 and rollers 32-38 are moved so that the element wire 22 draws a prescribed curvature, in a state where the wire 22 is guided by the first and fourth rollers 32 and 38. Through these operations, a three-dimensional concentratedly-wound coil is formed.
