The present invention relates to a silicone prosthesis comprising a silicone shell, which has superior texture and comfort when worn inside the body, minimizes stress concentration that may arise when wearing for a long time by eliminating the difference in physical characteristics and stress in all parts of the shell, due to the silicone prosthesis having uniform thickness, increases resistance to fatigue fracture so as to maximize the safety and the lifespan of the silicone prosthesis, and which controls the flow of the silicone toward various angles, thereby providing a round or an anatomical type silicone prosthesis having the shell with enhanced durability and entirely uniform thickness. The present invention also relates to a method for manufacturing the silicone prosthesis for forming the silicone shell of the silicone prosthesis by coating a mold body having the shape of the prosthesis with a silicone solution, and drying same in a drying device, wherein a jig is formed inside the drying device for fixing the mold body, so as to fix the mold body and maintain a level state until rotating and tilting in various angles to use the fluidity of the silicone for adjusting the thickness of the shell to be uniform, thereby providing a method for manufacturing the round or anatomical type silicone prosthesis having the shell with enhanced durability comprising a step for adjusting the thickness of the silicone.La presente invención se relaciona con una prótesis de silicona que incluye una cubierta de silicona, que tiene una textura y comodidad superiores cuando se implanta en el cuerpo, reduce al mínimo la concentración de esfuerzos que puede surgir cuando se utiliza durante un tiempo largo, eliminando la diferencia en las características físicas y el esfuerzo en todas las partes de la cubierta, debido a que las prótesis de silicona que tiene un espesor uniforme, incrementa la resistencia a la fractura por fatiga, de manera que se maximizan la seguridad y la vida úti
