PURPOSE: Provided are a polymer electrolyte excellent in ionic conductivity, which has excellent film formability and physical properties when producing a solid electrolyte by adding a liquid electrolyte to the polymer electrolyte, and an electrochemical element using the polymer electrolyte. CONSTITUTION: The polymer electrolyte is represented by the formula (I), wherein R1 is H or CH3, R2 and R3 are identically or differently C1-C5 alkyl or 3-acryloxypropylmethyl, k is an integer of 1-40, l is an integer of 1-40, and m is an integer of 0-100. And the solid electrolyte is produced by curing a mixture containing 10-90pts.wt. of the polymer electrolyte, 3-30pts.wt. of a lithium salt, 10-90pts.wt. of the liquid electrolyte, and an initiator. And the electrochemical element contains the polymer electrolyte.
