PROBLEM TO BE SOLVED: To provide the mounting structure of a ceramics sound absorption material panel with improved durability and reliability by increasing the stiffness in a frame body for making rigid the support by inserting a ceramic sound absorption board, suppressing the deflection of the sound absorption board, preventing a crack to be caused by the deflection it, increasing the stiffness in the mounting part of the ceramic sound absorption panel for preventing the damage in the frame body, and further preventing damage to be caused from the shock of the ceramics sound absorption board. SOLUTION: In a ceramics sound absorption board panel where the surrounding of a ceramics sound absorption board 2 made of a ceramics material is supported by a frame body 1 made of a steel material, a plurality of the ceramics sound absorption board 2 are received and are connected by a joint member, the joint member is formed of a Z-type steel, and is pinched at both the ends of the sound absorption board, the frame body 1 is formed of a channel steel with a lip in which a lip part 10 is projected from the channel steel of a U-shaped sectional surface, the frame body 1 and the support part for mounting are connected by spot welding, and wire netting is applied to both sides of the sound absorption board 2.
