Abstract
The present invention provides a separation membrane that is usable at a high temperature and a high pressure. The solvent-resistant separation membrane of the present invention has an average pore diameter of the separation membrane surface of 0.005 to 1 μm and includes a portion where a degree of cyclization (I1600/I2240) as measured by the total reflection infrared absorption spectroscopy is 0.5 to 50.
