Abstract
A separation membrane for a redox flow battery includes: a protective film formed on each of both surfaces of a sheet substrate along with pores, the sheet substrate having thereon a number of pores communicating between the both surfaces; and an ion-exchange membrane adhered to the protective film, the ion-exchange membrane having a matrix formed of an ion-exchange resin dispersed therein with an inorganic porous powdery body attached with the ion-exchange resin obtained as a result of sulfonating rosin.
