The present invention provides a separation membrane and a separation membrane element which are capable of exhibiting good water production performance and excellent in handleability and process passage. A separation membrane of the present invention is a separation membrane including: a separation membrane main body having a feed-side face and a permeate-side face; and a permeate-side channel member adhered to the permeate-side face of the separation membrane main body, in which the permeate-side channel member includes a composition containing at least a high-crystalline polypropylene (A) and satisfies the following requirements (a) and (b):
(a) a content of the high-crystalline polypropylene (A) in the composition is from 40 to 95% by weight; and
(b) the permeate-side channel member has a melting endothermic energy amount (”H) of from 20 to 70 J/g. |
