PROBLEM TO BE SOLVED: To provide a low-density non-combustible sheet or non-combustible molded product having a high level of non-combustibility and excellent lightweight properties. SOLUTION: There is provided a formed sheet obtained by adding a flocculant to a raw material slurry and wet forming the sheet in the flocculated state or a hot-press molded product of the formed sheet. The non-combustible sheet or the non-combustible molded product contains 30-90 mass% (solid content) of calcium silicate, or the calcium silicate and a hydrous inorganic compound, 0.4-20 mass% (solid content) of cellulose fibers, 3-40 mass% (solid content) of the sum total of the cellulose fibers and inorganic fibers, 5-40 mass% (solid content) of sepiolite and 1-20 mass% (solid content) of a synthetic polymer.
