Abstract: A production method for a fiber article includes: a contact step of, while transferring a plurality of first fibers, bringing a plurality of resin particles formed of high molecules that can be fiberized into contact with the plurality of first fibers; a first processing step of applying an external force to the plurality of first fibers brought into contact with the plurality of resin particles and narrowing gaps between fibers; and a second processing step of, by relieving the external force applied to the plurality of first fibers brought into contact with the plurality of resin particles, forming second fibers from the plurality of resin particles, the second fibers each having an outer diameter that is smaller than each of the first fibers and is set to a value in a range of 30 nm or more to 1.0 ?m or less, and forming a fiber composite including the first fibers and the second fibers.
