PROBLEM TO BE SOLVED: To provide a mammary prosthesis which reduces unnaturalness and facilitates wearing and removal.SOLUTION: A mammary prosthesis 1 includes: a first silicone rubber layer 2 a second silicone rubber layer 3 softer than the first silicone rubber layer 2 a soft layer 4 including a silicone gel and being softer than the second silicone rubber layer 3 a third silicone rubber layer 5 having the generally same hardness as the first silicone rubber layer 2. The soft layer 4 is arranged on an opposite side of the second silicone rubber layer 3 to a side arranged with the first silicone rubber layer 2. The third silicone rubber layer 5 is arranged on an opposite side of the soft layer 4 to a side arranged with the second silicone rubber layer 3. In the third silicone rubber layer 5, a recess part 6 recessed toward the soft layer 4 is formed. The second silicone rubber layer 3 and soft layer 4 are covered with the first silicone rubber layer 2 and third silicone rubber layer 5.SELECTED DRAWING: Figure 1
