PROBLEM TO BE SOLVED: To provide a fireproof perforated panel excelling in fireproof performance using less adiabatic thermal expansion material. SOLUTION: The fireproof perforated panel 1 has a fireproof plate-like member 2 having a large number of through holes 5a penetrating the front and rear sides, and the adiabatic thermal expansion materials 3 provided around at least the through holes 5a of the fireproof plate-like member 2. When the adiabatic thermal expansion materials 3 are overheated, the adiabatic thermal expansion materials 3 are expanded to block the through holes 5a. One side face of the fireproof plate-like member 2 is formed with recesses 4 around the through holes 5a, and the recesses 4 are filled with the adiabatic thermal expansion materials 3. The adiabatic thermal expansion materials 3 are formed with through holes 5b penetrating the adiabatic thermal expansion materials 3 and communicating with the through holes 5a.
