PROBLEM TO BE SOLVED: To provide a combustion-stopping composition, a combustion-stopping prepreg, and an incombustible decorative laminated sheet. SOLUTION: The combustion-stopping prepreg is produced by compounding a thermosetting resin as an organic resin component of a binder component, a silane coupling agent, an inorganic phosphoric acid ammonium salt or an inorganic phosphoric acid metal compound and a layered inorganic material, impregnating slurry composed of the organic resin as the binder component and a water-free inorganic material to a fiber sheet, drying the impregnation product, impregnating or applying the above composition to the dried prepreg and drying the product. A core layer composed of a prepreg obtained by impregnating a fiber sheet with slurry composed of an organic resin as a binder component and a water-free inorganic material and drying the product is laminated to a decorative layer interposing a combustion-stopping sheet and the laminate is hot-pressed.
