PROBLEM TO BE SOLVED: To provide a concrete member capable of reducing the used amount of organic fibers.SOLUTION: An arc-shaped concrete member includes: an organic fiber-mixed concrete layer that is formed in a concave-side surface layer part of the concrete member by using organic fiber-mixed concrete; a net-like material that is arranged on the organic fiber-mixed concrete layer; an arc-shaped stress material that has the net-like material attached on the concave side; and a concrete layer that is formed in the state of being superposed on a convex side with respect to the organic fiber-mixed concrete layer. |
