The invention provides a fireproof door and a fireproof door plate used by the same. The fireproof door comprises a door plate and a door frame installed at the periphery of the door plate in a sleeving manner, wherein distance location devices are arranged between the door frame and the door plate of the fireproof door, the distance location devices are uniformly arranged at intervals, buffer structures are arranged at the inner side of the door plate of the fireproof door, and the buffer structures are arranged at the middle positions of the two sides of the door plate respectively. The distance location devices are arranged between the door frame and the door plate of the fireproof door provided by the invention, the distance location devices are uniformly arranged at intervals, and by arranging the distance location devices, difficult opening for the fireproof door due to the own heat-expansion and cold-contraction effect of the fireproof door can be effectively prevented in case of a fire, and the losses of personal safety can be reduced; in addition, the buffer structures are arranged at the inner side of the door plate of the fireproof door, and through arrangements for second-layer buffer structures and selections for the positions of the buffer structures, secondary protection can be effectively carried out. The fireproof door is simple in structure, convenient to operate, low in production cost, and good in fireproof effect.
