摘要：
There is provided a strand that can reduce the trouble in constructing an object to which compression force is applied by the strand and that can keep the construction cost down.A strand 1 is placed in a bore hole provided in a wall or roof surface, and is gripped by a wedge in a tensioned state so as to apply a tensile force to the wall or roof surface. The strand 1 of the present invention includes a pipe-shaped member (corrugated tube 11) made of metal, and a plurality of metal wires 12 arranged on the outer periphery of the corrugated tube 11. The metal wires 12 are arranged to surround the corrugated tube 11 on the cross section of the corrugated tube 11.
