To provide a scaffolding board which is used for a single pipe and coupler scaffolding to be constructed, particularly, in a narrow place, which dispenses with a special mounting structure on the side of a pipe support, which enables the free adjustment of erection height, and which can prevent a step from being made between the adjacent scaffolding boards.

In the scaffolding board 1A, clamping implements 2A and 2B for a pipe are fixed in positions to deviate from each other on high and low sides opposite to each other via a mounting plate 11, at both ends of a scaffolding body 10. A difference of elevation between both the clamping implements 2A and 2B makes both the clamping implements 2A and 2B of the adjacent scaffolding boards 1A and 1A deviate from each other in the upper and lower positions, and makes them fixed to the pipe supports 3, respectively, so that top surfaces of both the scaffolding boards 1A and 1A can be set at the same height.
