[PROBLEMS] To provide high ionic conductivity near room temperature, low viscosity, nonflammability and excellent oxidation resistance, and to have characteristics required as a polymer electrolyte for lithium secondary batteries, capacitors and solar cells. A satisfactory ionic conductor is provided. An ion conductive compound (I) having a cyclic carbonate group and an ether group in a side chain and an electrolyte salt (II), wherein the ion conductive compound (I) has a fluoroether group in a side chain. An ionic conductor which is an amorphous fluorine-containing polyether compound or a cross-linked product thereof. [Selection figure] None |
