Provided is a mold release film, which does not have uneven thickness resulting from inhomogeneous stretching during drawing when molded with a die. The mold release film obtained from a fluorine-containing resin is characterized in that for the mold release film, the difference between the stress in the longitudinal direction of the film and the stress in the transverse direction is 1.80 MPa or less, the stress being a value obtained with a method conforming to ASTM D1708-02a under the conditions of a 120°C atmospheric temperature and a 100 mm/min pulling speed. |
