PROBLEM TO BE SOLVED: To provide a scaffolding board which has a scaffolding board body capable of reducing costs by making weight as light as possible, and capable of also securing sufficient strength. SOLUTION: In the scaffolding board body 4 of the scaffolding board, both side wall portions 2 and 2 are protruded downward from both the right and left side wall portions 2 and 2 of a top board portion 1, respectively; and supporting wall portions 3 and 3 are protruded inward from lower ends of both the side wall portions 2 and 2 in the state of facing each other, respectively. The scaffolding board body 4 is molded by roll forming of one steel plate material. A reinforcing rib 7 protruding downward by about a half to a quarter of the height H of the side wall portion 2 is integrally formed in the width-direction central portion of the top board portion 1 throughout the length-direction area of the top board portion.
