The present invention addresses the problem of providing an artificial skin preparation to be used in treating a wound part using as an artificial skin a dried collagen vitrigel membrane, said artificial skin preparation requiring no stitching, etc., scarcely causing contamination with exudate, and being free from the risk of secondary damage in the exchange thereof. The artificial skin preparation, which comprises at least an adhesive film, an adhesion-preventing sheet and a dried collagen vitrigel membrane in this order, is characterized in that: the adhesion-preventing sheet has a sufficient size for preventing the sticking of the collagen vitrigel membrane to an adhesive layer of the adhesive film and is patched to the adhesive layer of the adhesive film, said adhesive layer being disposed corresponding to the position of the dried collagen vitrigel membrane; and, during the artificial skin preparation is patched, the dried collagen vitrigel membrane is fixed to the surface of the adhesion-preventing sheet and held thereon, but, when the adhesive film is peeled off, the dried collagen vitrigel membrane can be easily separated from the adhesion-preventing sheet.
