PROBLEM TO BE SOLVED: To provide a wooden fire door which exerts sufficient fire protective performance and is produced at a relatively low cost. SOLUTION: The wooden fire door is formed of a core member 20 consisting of paulownia members 21 to 23 as main bodies, and decorative plywood portions 40 arranged on surfaces. The wooden fire door is comprised of a fire resistive paint layer 30 which is formed between the core member 20 and each decorative plywood portion 40, and a slipout preventive structure 51 for preventing the fire resistive paint layer 30 from slipping out of the core member 20.
