PROBLEM TO BE SOLVED: To provide a portable working platform capable of performing a lifting from a ladder-like main leg to a top plate and working on the top plate, capable of securely preventing a worker from falling from a top plate by a tripping therefrom, hard for the worker to trip on the top plate, and capable of increasing safety in the portable working platform in which the top plate is installed across a pair of ladder-like main legs. SOLUTION: In this portable working platform 1 formed by installing the pair of ladder-like main legs 4, a plurality of button-like projections 11 capable of being sensed by the bottom of feet are formed on the top plate 3 at proper intervals. The button-like projections 11 are formed in those projected parts formed integrally with the top plate 3, or formed separately from the top plate 3 and formed of a cap and a leg part, and detachably inserted into a slip-prevention hole 2 formed in the top plate 3.
