To provide a polyelectrolyte that contains only a small amount of ionization aid but yet has excellent ion conductivity, small interfacial resistance, and excellent productivity.SOLUTION: A polyelectrolyte contains an alkali metal salt, an ionization aid, inorganic particles and a polymer. The inorganic particles have polar groups on their surfaces, wherein at least some polar groups are partially substituted with alkali metal cations. The polymer is polyarylene sulfide.SELECTED DRAWING: None 【課題】少量の電離助剤量においてもイオン伝導度に優れ、界面抵抗が小さく、さらに、生産性に優れるポリマー電解質を提供することを課題とする。【解決手段】アルカリ金属塩、電離助剤、無機粒子およびポリマーを含有するポリマー電解質であり、前記無機粒子が表面に極性基を有し、少なくとも一部の極性基の一部がアルカリ金属のカチオンで置換されており、前記ポリマーがポリアリーレンスルフィドであることを特徴とする、ポリマー電解質。【選択図】なし
