PROBLEM TO BE SOLVED: To provide a method for producing a nonwoven fabric through suppressing its longitudinal extension tending to occur in producing a nonwoven fabric from fibers freed from components removable by an aqueous solvent, and for ensuring its own touch feeling not to be impaired due to polymer addition thereto, or the like. SOLUTION: The method for producing a nonwoven fabric formed of extrafine fibers each 0.0001-0.5 dtex in fineness includes the following steps A, B, C and D, or the following steps A, B, D and C (wherein, including the case where the steps B and D are conducted simultaneously), in this order: the step A of integratedly laminating a nonwoven fabric formed of fibers capable of producing extrafine fibers each 0.0001-0.5 dtex in fineness by removing components removable by an aqueous solvent and a fabric formed of the components; The step B of producing the extrafine fibers by conducting a treatment with the aqueous solvent; The step C of conducting a fluid jet treatment; and The step D of removing the residuals of the integratedly-laminated fabric (i.e. the fabric comprising the components) by conducting a treatment with the aqueous solvent.
