To produce a helical cord that forms an elliptical shape will be manufactured so that the length-to-width ratio or the dimensions of the shaped form of the cord that is shaped in the length direction can be changed.

A cord C is passed successively to through-holes 21H and 22H in a stationary and a movable shaping body 21 and 22 opposite each other in a shaping device 20. At this time, the movable shaping body 22 is moved along the stationary shaping body 21 by a moving apparatus, the through-holes 21H and 22H are brought off-center, and the cord C passing between the off-centered through-holes 21H and 22H is shaped by being bent and deformed. The moving apparatus is also provided with first and second displacement mechanisms that displace the movable shaping body 22 in the X and Y directions. The movable shaping body 22 is thus rediprocatingly displaced by amounts of displacement individually set synchronized to the two directions, the movable shaping body 22 is moved continuously interlocked to the displacement in the two directions, and the cord C that is passed through is shaped.
