PROBLEM TO BE SOLVED: To provide reinforced concrete structure facilitating the execution of works and obtaining high strength by burying polyacetal fibers, which are lightweight, can be worked at a normal temperature and strength of which is not lowered by a flaw, into a concrete member as a reinforcing material. SOLUTION: The reinforced concrete structure is constituted in such a manner that main reinforcements 2 such as a deformed bar, round steel or the like are arranged as reinforcing materials in the axial direction of a concrete member 1, polyacetal fibers 3 having a modulus of tension from 20 GPa to 150 GPa and a mean outside diameter from 0.4 mm to 100 mm are wound and disposed on the main reinforcements 2 are reinforcing materials in the direction orthogonal to the axial direction of the concrete member 1 and the main reinforcements 2 and the polyacetal fibers 3 are buried integrally into the concrete member 1.
