PROBLEM TO BE SOLVED: To provide a biaxially drawn polyester film which is superior in boring sensitivity when used as a heat-sensitive stencil sheet, is superior in resolution at the time of printing, printing grade property and density, and can be used as the heat-sensitive stencil paper of a high quality. SOLUTION: This film for a heat-sensitive stencil sheet is a biaxially drawn polyester film of which the melting point is 140 to 250°C, and of which the thickness is 1.0 to 3.5μm. Unevenness in the thickness in the width direction is 18% or lower, and the amplitude of a local wrinkle in the width direction is 3.0 mm or lower. COPYRIGHT: (C)2007,JPO&INPIT
