PROBLEM TO BE SOLVED: To provide a polymer laminate which can obtain abrasion resistance equivalent to that of a glass plate even in severe abrasion test conditions. SOLUTION: In the polymer laminate, a crosslinked resin layer 3-100μm in thickness and a silicon oxide layer 4-25μm in thickness are laminated in turn on at least one side of a polymer substrate. The crosslinked resin layer has a Young's modulus of 5-15 GPa in nano-indentation measurement under the maximum load of 1 mN, and the silicon oxide layer has a Young's modulus of 45-125 GPa in the same conditions as above and the value of displacement at the end point of a load/displacement curve of 0-40% of the value of maximum displacement.
