According to the present invention, an immunoisolation membrane is provided at the boundary between the inside and the outside of the transplantation chamber, the immunoisolation membrane includes a porous membrane, and the porous membrane is after being immersed in water at 90 ° C. for 3 hours. The maximum heat shrinkage of the heat shrinkage in the film surface direction is 0.00% or more and 5.00% or less, and the maximum heat shrinkage and the minimum heat shrinkage of the heat shrinkage in the film surface direction. There is provided an implantation chamber having a difference of 0.00% to 1.30%, and an implantation device in which a biological constituent is included in the implantation chamber. The implantation chamber of the present invention is highly durable and can maintain the contained biological constituents for a long period of time.本発明により、移植用チャンバーの内部と外部との境界に免疫隔離膜を有し、上記免疫隔離膜が多孔質膜を含み、上記多孔質膜は、９０℃の水に３時間浸漬した後の膜面方向の熱収縮率のうち最大の熱収縮率が０．００％以上５．００％以下でありかつ上記膜面方向の熱収縮率のうち、最大の熱収縮率と最小の熱収縮率との差が０．００％以上１．３０％以下である移植用チャンバー、ならびに上記移植用チャンバーに生物学的構成物が内包されている移植用デバイスが提供される。本発明の移植用チャンバーは耐久性が高く内包される生物学的構成物の長期維持が可能である。
