To provide a technology of utilizing a linear wire, such as an existing electric wire, in a spirally wound state.

A curl cord device 1 includes a coil spring 10 with elasticity which is formed into a spiral shape and expandable/contractible in the center line direction, and clips 30 to hold an electric wire 2 in a spiral shape by detachably fixing the electric wire 2 having a circular cross-sectional surface along a coil 11 of the coil spring 10. Moreover, one binding band 40 is used to bind the electric wire 2 at a portion in the vicinity of the upper end of the coil 11 of the coil spring 10, and the other binding band 40 is used to bind the electric wire 2 at a portion in the vicinity of the lower end of the coil 11 of the coil spring 10.
