An electrolyte membrane for a fuel cell having excellent durability, a binder for forming an electrode catalyst layer, an anion exchange resin capable of producing a battery electrode catalyst layer, an electrolyte membrane for a fuel cell formed from the anion exchange resin, and an electrode catalyst layer Provided is a fuel cell comprising a forming binder and a battery electrode catalyst layer, and an electrolyte membrane for the fuel cell or a battery electrode catalyst layer. A divalent hydrophobic group consisting of a single aromatic ring or consisting of a plurality of aromatic rings bonded to each other via a divalent hydrocarbon group, a carbon-carbon bond, or the like, is connected via an ether bond. A hydrophobic unit bonded to each other and a single aromatic ring, or a plurality of aromatic rings bonded to each other via a divalent hydrocarbon group or a carbon-carbon bond, at least one of the aromatic rings being an anion A hydrophilic unit in which divalent hydrophilic groups having an exchange group are bonded to each other through a carbon-carbon bond is bonded through a carbon-carbon bond.
