The present invention relates to a hyaluronate nonwoven fabric composed of hyaluronate fibers and a manufacturing method therefor, wherein a nonwoven fabric composed of only pure hyaluronate is provided without the addition of any heterogeneous fiber, such as PVA which is a binding fiber essentially added during a wet-laid nonwoven fabric manufacturing process, so that a nonwoven fabric composed of only hyaluronate fibers with excellent human compatibility and without cytotoxicity, skin irritation, and the like can be provided, and thus can be used as patches for cosmetic patches, wet wound dressings, tissue adhesion barrier membranes, and the like.
