There are provided microfibers that generate less formaldehyde and acetaldehyde and have a favorable fiber openness, a fiber molded body using the microfibers, and a method for producing the same. The method for producing a fiber molded body of the present invention is a method for producing a fiber molded body comprising molding of a fiber mixture, wherein the fiber mixture comprises microfibers, wherein the content of the microfibers in the fiber mixture is 5 mass % or more, wherein, in the microfibers, an amount of an oil adhered is 0.1 to 1 mass %, a total amount of ethylene oxide units and propylene oxide units generated is 0.01 to 0.5 mass %, and a single fiber fineness is 0.01 to 0.5 dtex.
