PROBLEM TO BE SOLVED: To provide a polylactic acid film which is less likely to be peeled while having excellent piezoelectric characteristics, and to provide a piezoelectric laminate using the same.SOLUTION: The uniaxially oriented film for piezoelectric laminate is composed of poly L-lactic acid or poly D-lactic acid having optical purity of 80 mol% or higher, and contains an impact resistance modifier in the range of 0.1-10 mass%, with reference to the mass of the uniaxially oriented film. |
