The present invention relates to a method of manufacturing a hyaluronate film and a hyaluronate film manufactured thereby, and more particularly to a method of manufacturing a hyaluronate film through a solvent-casting process or using an automatic film applicator that facilitates mass production and to a hyaluronate film manufactured thereby, which is useful as a mask pack for cosmetics, a patch for medicaments and medical devices, a film-type adhesion inhibitor, etc. Unlike conventional liquid products, the hyaluronate film according to the present invention has a dry surface and thus entails no concern about microbial contamination, is easy to produce/manage/distribute/use, and has superior mechanical properties, whereby it can be utilized for various applications such as packs, patches, artificial skin and the like for cosmetics, medicaments, and medical devices.
