Zusammenfassung:PURPOSE:To provide the title composition having a high ionic conductivity, excellent moldability, etc., by incorporating a polymeric substance having OH groups at least part of which are phosphated and converted into an alkali metal salt. CONSTITUTION:A polymeric substance having OH groups as side chains, such as polyvinyl alcohol or cellulose, is phosphated and is neutralized with a base of an alkali metal (e.g., Li). In this way, a polymeric substance having OH groups as side chains at least part of which are phosphated and converted into an alkali metal salt is produced. This ionically conductive composition can the molded into a film, a fiber or the like and can be suitably used as a material for a film battery, an electrochromic element or the like.
