Zusammenfassung:	PURPOSE:To lower dependence of ion conductivity on salt concentration and make it possible to retain high ion conductivity even in high salt concentration by making a polymer matrix of PEO chains and PPO chains being polymerized reciprocally and regularly. CONSTITUTION:Ion conductivity is diffusion transference of a dissociated electrolytic salt, which is dissolved in polymer matrix by solvent, in the matrix along to the electric field. The important thing is the repeated number and repeated form of ethylene oxide(EO) unit and propylene oxide(PO) unit. The repeated number (X) of EO unit in the formula (I) is 8-30, the repeated number of (Y) of PO to the EO repeated number is 1-5, and further block copolymer unit of PEO-PPO is included with a number so as to introduce >=3 PEO units. The length of an ionic dissociation group between branched chains of the polymer matrix thus becomes long. As a result, the dependence of ion conductivity on salt concentration lowers and decrease of ion conductivity by addition of a salt in a high concentration is scarcely observed.
