| abstract | Provided is a film manufacturing method capable of reducing the heat shrinkage rate in the longitudinal direction without imposing a heavy load on film manufacturing process equipment while maintaining good flatness. SOLUTION: A longitudinal stretching process for stretching a film in a longitudinal direction, a transverse stretching process for stretching a film in a width direction by a tenter device, and a plurality of transport rolls having a temperature lower than the glass transition temperature Tg of the film, V is the film transport speed when the cooling process and the transverse stretching process are finished, and the tension roll mechanism 9 is provided, and the rotational speed of the transport roll located upstream in the transport roll group is Va. And when the rotation speed of the roll located second from the upstream in the transport roll group 6 is Vb, it has a longitudinal stretching step, a lateral stretching step, and a cooling step in this order, and Va / V is 0.980 to The manufacturing method of the film which is less than 1.000 and Vb / Va is 1.001-1.020.
