The invention provides a fireproof door. The fireproof door comprises a door plate and a fire-retardant fireproof doorsill, and the doorsill comprises a first sealing portion 0.6-1.2cm in height, a second sealing portion 4-5cm in height and a door plate closing sunken portion between the first sealing portion and the second sealing portion, wherein the first sealing portion with the arc-shaped upper surface is lower than the second sealing portion. The fireproof door has the advantages that since the doorsill comprises the first sealing portion, the second sealing portion and the sunken portion between the first sealing portion and the second sealing portion, the fireproof door is better in sealing, fireproof and smokeproof effect and gains more time for protection and evacuation; door closing is facilitated through the arc shape of the first sealing portion and the horizontal plane in the middle of the upper surface of the first sealing portion; the second sealing portion fits the door plate tightly through a cuboid of the second sealing portion and a bottom plane shape of the door plate, so that sealing and smokeproof effects are further improved.
