PROBLEM TO BE SOLVED: To provide a sheet forming device which allows forming of an orderly shaped, high dimensional precision, high quality sheet by controlling delivery fluctuation of an elastic material to a rolling section, and further can absorb abrupt change of internal pressure of a material storage section. SOLUTION: In the sheet molding device equipped with a material supply section 1 to supply an elastic material W, a material storage section 3 to temporarily store the elastic material W supplied from the material supply section 1, and a material rolling section 2 to roll the elastic material W stored in the material storage section 3, a material pressing mechanism 4 is prepared for putting a preset constant pressure from the upper side to press the elastic material W reserved in the material storage section 3, and the area of a material pressing surface 41a of a material pressing member 41 composing the material pressing mechanism 4 is set to 30-95% of that of an upper opening 31 of the material storage section 3.
