An outer bag in which a core is contained in a movable state is made of a non-assimilatable material to function as an outer artificial coating. The outer bag includes a sheet-shaped base and a large number of convexes (14, 15) and/or concaves 14 formed integrally with the sheet-shaped base and disposed on an outer surface of the sheet-shaped base. Therefore, there is no probability that a breast prosthesis implanted into an implantation-scheduled space in a chest is deformed due to capsular contracture to decrease its surface area. There is no probability that free movement of the breast becomes poor. Even though the construction is simple, a breast prosthesis having a good outer artificial coating can be provided.
