PROBLEM TO BE SOLVED: To reduce variation in coil dimensions after winding in a coil winding device 1 for winding both ends of a linear material 2 on cores 12 and forming them into a coil shape. SOLUTION: The coil winding device 1 includes two winding mechanisms 7, 8, placed opposite to each other, that wind up a linear material 2 and is so constructed that both ends of the linear material 2 are respectively wound up in a coil shape by the winding mechanisms 7, 8. Synchronization control is carried out so that the rotation of the core 12 of the winding mechanism 7 and that of the core 12 of the winding mechanism 8 are synchronized with each other. Both ends of the linear material 2 is respectively wound along the cores 12 to form a coil. Thus the position of the core 12 of the winding mechanism 7 and the position of the core 12 of the winding mechanism 8 are equal to each other at an equal time. Therefore, it is possible to wind both ends of a linear material 2 with equal tension at an equal time. As a result, the degree of plastic deformation does not vary from end to end of the linear material 2; therefore, it is possible to reduce variation in the dimensions of the wound coil.
