Abstract
An electrolyte membrane () includes a base material layer () containing a hydrocarbon-based electrolyte as a main component, and a surface layer () laminated with the base material layer (). The surface layer () is a layer containing, as a main component, a polymeric material having a hydroxyl group and a proton conductive group. The polymeric material that constitutes the surface layer () contains, for example, a first polymer having a hydroxyl group, and a second polymer having a proton conductive group. A matrix is formed by cross-linking the first polymer, and the second polymer can be held in the matrix.
