Abstract
The electrolyte membrane of the present disclosure includes a phase A forming a matrix phase, and a phase B. The phase B is continuous from a first principal surface of the electrolyte membrane to a second principal surface of the electrolyte membrane opposite to the first principal surface. The phase B includes a graft polymer having a main chain and a graft chain. The graft chain has a functional group having anion-exchange ability. The main chain preferably has no functional group having anion-exchange ability. The electrolyte membrane of the present disclosure can reliably maintain the function as a separation membrane even when decomposition reaction by a peroxide occurs.
