PROBLEM TO BE SOLVED: To provide a method for producing a laminated fiber aggregate, by which the laminated fiber aggregate produced by directly accumulating fibers spun by an electrostatic spinning method and comprising two or more fiber aggregate layers having different average fiber diameters, respectively, can more simply be produced with simpler installations than conventional those. SOLUTION: This method for producing the laminated fiber aggregate comprising two fiber aggregate layers satisfying relations having two or more fiber aggregate layers produced by directly accumulating the fibers spun by the electrostatic spinning method, comprising the fibers produced from the same resin, and having mutually different average fiber diameters is characterized in that the two fiber aggregate layers are produced from the same spinning dope in spinning spaces having different relative humidity, respectively.
