To provide a jumping rope which is rich in flexibility, and hard to generate elongation.

A flexible and non-stretchable core material 30 is provided, and a large number of engaging members 31 comprising a rigid material are immovably fixed to the core material 30 in such a manner that larger diametrical sections 33 and smaller diametrical sections 32 may be alternately formed at intervals in the longitudinal direction of the core material 30 on the surface of the core material. On such a long-sized and bendable core body 3, a coating layer 2 comprising a flexible resin or elastomer is coated for this jumping rope.
