PROBLEM TO BE SOLVED: To obtain excellent durability by forming a finishing material in which ligneous plates and inorganic plates having an inorganic foamed body as a core layer on the obverse and reverse layers of mineral fiber, inorganic powdery material, and a binder, are integrally laminated alternately through an adhesive. SOLUTION: An inorganic composite finishing material A in which inorganic plates 1 and ligneous plates 2 are alternately laminated and the inorganic plates are arranged in the uppermost layer and the lowermost layer is formed. The ligneous plate 2 is made of veneer or MDF, etc. The inorganic plate 1 is constituted of three layers that obverse and reverse layers composed of a mineral fiber, an inorganic powdery material, and a binder as essential components and a core layer having an inorganic foamed body and a binder as essential components are integrally laminated and the specific gravity is set within a range of 0.6-0.9 as a whole. Then, the inorganic plates 1 are disposed in the uppermost layer, the central layer, and the lowermost layer and veneers 2 are disposed between mutual inorganic plates 1 to adhere the inorganic plate 1 and the veneers 2 and mutual veneers 2 with a melamine adhesive. Therefore, this composite finishing material excellent in bending strength and nail-retentive force and also water-absorbing size-stability can be obtained.
