A stage for clean room is provided to minimize the disturbance of air flow by employing a perforated plate with the porosity of 65~75% and to improve work efficiency by moving on the frame via the mobile device. A stage(100) for clean room comprises a support frame(10) settled on the upper side of a filter frame installed in the clean room, a perforated plate(20) combined with the support frame and supporting a worker. The perforated plate has a plurality of perforations arranged at regular intervals with the porosity of 65~75% in order to minimize disturbance of the air flow within the clean room.
