PROBLEM TO BE SOLVED: To provide an accumulation product of nanofibers having a stable performance. SOLUTION: Provided is a method for producing the nanofibers with a nanofiber-producing apparatus 100 includes a jetting means 201 for jetting a raw material liquid 300, a charging means 202 for charging the raw material liquid 300, a gas flow-forming means 203 for forming a gas flow, an accumulation means 101 for accumulating the nanofibers 301, a conveying means 104 for moving the accumulation means 101, a guide means 206 for guiding the nanofibers 301, a suction means 102 for sucking the gas flow, an area-regulating means 103 for regulating a suction area, the first pressure-measuring means 241 for measuring a pressure in the guide means 206, and the second pressure-measuring means 107 for measuring a pressure in the area-regulating means 103. The method includes a pressure difference-calculating step for calculating a difference between the measurement result of the first pressure-measuring means 241 and the measurement result of the second pressure-measuring means 107 as a pressure difference, and a production condition-controlling step for controlling nanofiber production conditions on the basis of the calculated pressure difference.
