The invention discloses a fireproof door, and belongs to the technical field of fireproof doors. The fireproof door comprises a door leaf, a fireproof lock, a fireproof door handle, fireproof hinges, a door frame and an electromagnetic induction type fireproof door closer. The door frame of a double-L-shaped structure comprises a front contact portion, a middle connection portion and a rear contact portion. The fireproof door has the advantages that the fireproof door is simple in structure and good in fireproofing and heat insulation effects; door frame deformation is prevented, and a gap between the door leaf and the door frame is further reduced; the fireproof door has high sensitivity and is closed timely, so that fire spread and smoke diffusion are stopped effectively.
