PROBLEM TO BE SOLVED: To provide a polyester film for a heat-sensitive stencil printing original paper of high sensitivity, which excels in perforation sensitivity, and is improved in the degree of resolution, in a plate making strain and in plate wearability or the like. SOLUTION: The polyester film for a heat-sensitive stencil printing original paper of high sensitivity is a biaxially oriented polyester film having a thickness of 1.0 to 7.0μm comprising three or more polyester compounds, in which Young's modulus of the film is 3,000 MPa or more, and a main dispersion temperature E" (t) of the dynamic viscoelasticity temperature characteristic obtained by the dynamic viscoelasticity method is 60 to 75°C.
