    • Objects of the invention are to provide an ion-conductive polymer electrolyte for electrochemical device which has low volatility, is excellent in moldability and processability, has high compressive strength, has satisfactory ionic conductivity in a wide temperature range from ordinary to high temperatures, and has satisfactory chemical stability in high-temperature environments and to provide a secondary battery which employs the electrolyte and which has a practically sufficient output in a wide temperature range and has satisfactory safety and reliability in high-temperature environments. The polymer electrolyte for electrochemical device of the invention and the secondary battery employing the electrolyte include a polymer of a polymerizable boron-containing compound represented by formula (1), a high-molecular compound represented by formula (2), and an electrolyte salt. In formula (1), B represents a boron atom; Z 1 , Z 2 , and Z 3 each independently represent a polymerizable functional group having an unsaturated double bond; A 11 O, A 12 O, and A 13 O each independently represent an oxyalkylene group having 2-6 carbon atoms; and h, i, and j, which each indicate the average number of moles of the oxyalkylene group added, each independently are 1-10. €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒR 1 O-(A 2 O) k -R 2 €ƒ€ƒ€ƒ€ƒ€ƒ(2) In formula (2), R 1 and R 2 each independently represent a hydrocarbon group having 1-10 carbon atoms; A 2 O represents an oxyalkylene group having 2-6 carbon atoms; k, which indicates the average number of moles of the oxyalkylene group added, is 4-20; and the groups A 2 O may be the same or different.
