An object of the present invention is to provide a tension mooring line for a tension moored floating body that can equalize the tension generated in each tension mooring line without adjusting the length of each tension mooring line in each mooring bundle that supports the tension moored floating body, thereby preventing resonance with the off-shore wave period. This object is achieved by providing a mooring line for a tension moored floating body that connects between a connecting part 5b formed on the tension moored floating body and a seabed mooring part 9 fixed to the seabed 103, wherein tension is generated in the tension mooring line 7 by the buoyancy created due to the tension moored floating body 5 being connected by the tension mooring line 7, and the tension moored floating body 5 can be maintained in a tension moored state. The tension mooring line 7 is configured such that a low rigidity mooring line 7b, which has low tensile rigidity calculated by multiplying the Young's modulus of the line material by the cross-sectional area, and a high rigidity mooring line 7a, which has higher tensile rigidity than the low rigidity mooring line 7b, are connected via a connector.
