Abstract: The invention relates to a method for producing a breast prosthesis in which a two-component addition cross-linkable soft elastic silicone rubber composition is introduced into a synthetic resin film constituting the inside and the outside of the prosthesis. The synthetic resin film filled with the as yet uncross-linked silicone rubber composition is arranged in a mold and silicone rubber composition is caused to cross-link with the development of heat. In order to improve upon the known method for the production of breast prostheses that the holding members to be attached may simply be arranged on the breast prosthesis and that the finished breast prosthesis has a neat appearance, in accordance with the invention at least one holding element, preferably in the form of an adhesive strip, is applied to the inner side of the breast prosthesis, by the activation of a hot-melt adhesive.
