Abstract: A method for producing a shaped article includes a second web forming step, in which a mixture containing fibers and a binding material is deposited in the air, the binding material containing starch and an alkali metal salt; a moistening step, in which the mixture is supplied with water; and a sheet-forming step, in which heat and pressure are applied to the mixture supplied with water to give a sheet. The alkali metal salt content of the binding material is 2.0% by mass or less of the total mass of the starch.
