PROBLEM TO BE SOLVED: To provide a reinforcing metal fitting in which rigidity comparable to a conventional reinforcing metal fitting is obtained by using bar steel for reinforced concrete having a wire diameter thinner than a conventional reinforcing bar while the filling of aggregate is not obstructed even when bar steel is arranged doubly in a reinforcing bar for the opening section of a concrete wall. SOLUTION: The reinforcing metal fitting 1 composed of a frame body 2, in which each corner section of a quadrilateral are projected in a U shape in the oblique external direction and formed in a bobbin-shaped external shape, and rod-shaped bodies 3a, 3b, 3c and 3d arranged in parallel with the external sides of each projecting section on the insides of each projecting section is formed.
