The present invention includes a collagen solution production stage in which collagen is dissolved in an acidic solution to produce a collagen solution, a cross-linking stage in which the collagen solution is physically cross-linked by irradiating with ultraviolet rays, and drying in which the cross-linked collagen is naturally dried. A method for producing a collagen film using ultraviolet rays, a collagen film produced using the method for producing a collagen film using ultraviolet rays, and a wound dressing produced using the collagen film, The present invention relates to a biomaterial such as an artificial tympanic patch, a dental shielding film, an artificial cornea, an artificial lens, an anti-adhesion film, a drug delivery preparation, and an artificial organ.
