Abstract
A separation membrane complex includes a porous support and a separation membrane formed on the support. The separation membrane has a small void. A small void index Iexpressed by (Σ(S))/(S) and indicating the abundance ratio of small voids is higher than or equal to 10×10, and a large void index Iexpressed by (Σ(S))/(S) and indicating the abundance ratio of large voids is lower than 200×10, where Sis the surface area of the separation membrane, Sis the area per small void, and Sis the area per large void. Accordingly, the separation membrane complex can achieve a high separation ratio.
