Provided is an aid for preventing wound separation having an excellent effect of preventing the separation of a wound, which is an open scarring formed by injuring a body part, and being easy to use and to attach.The aid for preventing wound separation comprises: a wound separation-preventing part covering a wound and the peripheral tissues holding parts having a function of bringing the wound separation-preventing part into close contact with the wound and the peripheral tissues and holding the same and a shrinkage preventing part having a function of keeping the wound separation-preventing part in a state being appropriately stretched in the direction along the wound separation and thus preventing the shrinkage of the wound separation-preventing part. The aid for preventing wound separation has such a function that the distance of the shrinkage, in the direction along the wound separation, accompanying the attachment of the wound separation-preventing part becomes equal to or greater than the distance of the shrinkage, in the direction along the wound separation, accompanying the attachment of the holding parts. The aid for preventing wound separation is attached by: stretching the wound separation-preventing part in the direction along the wound separation in the state where the distance of the shrinkage, in the direction along the wound separation, accompanying the attachment of the wound separation-preventing part becomes equal to or greater than the distance of the shrinkage, in the direction perpendicular to the direction along the wound separation, accompanying the attachment of the wound separation-preventing part, bringing the wound separation-preventing part into close contact with the wound and the peripheral tissues thus attaching the wound separation-preventing part by fixing by the holding parts and then removing the shrinkage preventing part.La présente invention concerne une aide destinée à prévenir louverture dune plaie, qui possède un excellent ef
