A practical cable made of a high strength fiber composite material is provided, which has high and stable strength, in addition, has even axial tension against bending and thus has a stable shape, and can be wound on a reel without shape deformation, and is hardly buckled when it is inserted into a hole or cylinder. The cable is formed by singly twisting a plurality of high strength fiber composite materials is used as a strand, and a plurality of the strands are twisted together at a twist angle of 2 to 12 degrees in a direction opposite to a twist direction of the strands, so that a double twist structure is made.
