PROBLEM TO BE SOLVED: To develop a new incombustible panel which further adds a function as a bearing wall to an existing inorganic incombustible panel excellent in usability and functionality without impairing the advantages.SOLUTION: An incombustible panel P of the present invention includes a board principal member 1 obtained by forming an inorganic material in a low-density plate shape, and board reinforcing materials 2 laminated and fixed to one or both of the surfaces of the board principal member 1. The board reinforcing material 2 comprises a wood core material 4 thinner than the board principal member 1, and outside shell plates 5 using a metal material and laminated and fixed to one or both of the surfaces of the wood core material 4. The metal outside shell plate 5 has a smaller area than that of the board principal member 1, and an adjustment allowance 21, in which the outside shall plate 5 does not exist, is formed in the peripheral edge of the board principal member 1 in a laminated state. |
