A structure of a vacuum adsorbing working platform includes a lower body and an upper body. The lower body has a plurality of channels, and the top of the lower body has a plurality of cross grooves which extend transversely and longitudinally. The channels communicate with the grooves, and they connect to an induction pump. The upper body attached on the lower body has a plurality of ventilation holes passing through the upper body and relative to the grooves, thereby the structure of the working platform is formed which provides better suction.
