PROBLEM TO BE SOLVED: To provide a technology of adequately sealing one end of a separation membrane structure main body.SOLUTION: A separation membrane structure includes: a separation membrane structure main body having a base material formed of a tubular porous inorganic material and a separation membrane formed on an inner surface or an outer surface of the base material; and a seal member which seals one end part of the separation membrane structure main body and is formed of an elastic material. The seal member includes an opening covering part which covers an opening of the one end part of the separation membrane structure main body, and a surface covering part which covers at least a part of a surface with the separation membrane formed out of the inner surface and the outer surface of the separation membrane structure main body. The opening covering part and the surface covering part are integrally formed.SELECTED DRAWING: Figure 1 【課題】分離膜構造体本体の一端を適切に封止する技術を提供する。【解決手段】管状の多孔質無機材料からなる基材と、基材の内表面又は外表面に形成された分離膜と、を備える分離膜構造体本体と、分離膜構造体本体の一方の端部を封止する、弾性材料から成るシール部材と、を備え、シール部材は、分離膜構造体本体の一方の端部の開口を被覆する開口被覆部と、分離膜構造体本体の内表面および外表面のうち、少なくとも分離膜が形成された面の一部を被覆する表面被覆部と、を備え、開口被覆部と表面被覆部とは、一体的に形成されている、分離膜構造体。【選択図】図１
