Abstract:
The present invention was accomplished in order to provide a method for producing a sheet containing fine fibers, which enables production of a sheet containing fine fibers without producing wrinkles. The present invention provides a method for producing a sheet containing fine fibers comprising a coating step of coating a dispersion containing fine fibers having a fiber diameter of 1000 nm or smaller on a base material, and a drying step of drying the dispersion containing fine fibers coated on the base material to form a sheet containing fine fibers.
