PROBLEM TO BE SOLVED: To provide an easily manufacturable reinforcing truss reinforcement having large strength, its manufacturing method, a precast concrete slab, and a precast steel plate. SOLUTION: This reinforcing truss reinforcement 1 is integrated by joining at least one of mutual vertically overlapped upper end reinforcements 2, mutual lower end reinforcements 3 and mutual lattice reinforcements 4, by vertically overlapping truss reinforcements 5, 6 and 7 in a plurality, by forming the truss reinforcements 5, 6 and 7 of connecting one upper end reinforcement 2 arranged in an apex angle part of a triangle and two lower end reinforcements 3 arranged in two corner parts in a lower part by the waveform lattice reinforcements 4.
