PROBLEM TO BE SOLVED: To provide a cord improving bending and compression durability without causing an increase in weight. SOLUTION: The cord 10 comprises a wrapping filament 16 wrapped around a cord body 14 composed of a plurality of filaments 12 with an amplitude in the direction intersecting the cord radial direction at right angles in a helical form. Thereby, the wrapping filament 16 can be deformed in the direction to lengthen the wavelength to relax tension applied to the wrapping filament 16 when the tension is applied to the wrapping filament 16. Thereby, the breaking of the wrapping filament 16 is suppressed. Since the wrapping filament 16 is wrapped around the cord body 14 with the amplitude in the direction intersecting the cord radial direction at right angles in the helical form, the contact surface area with each filament 12 constituting the cord body 14 is minimized to suppress the abrasion of the wrapping filament 16.
