Abstract

To provide a manufacturing method of a biaxially stretched film for smoothly introducing a base material film after biaxial stretching into a heat treatment device, and a biaxially stretched film manufacturing apparatus therefore. In the biaxially stretched film manufacturing apparatus, an energizing device 80, which has a pair of energizing rolls 81 for energizing both end parts of the base material film 2 to the outside in the width direction of the base material film 2, is provided on the upstream side of the heat treatment device 40. The energizing rolls 81 are provided as one set composed of two rolls and has cylindrical rotary parts which hold the base material film 2 from both sides thereof to apply linear pressure to the base material film 2 and can be reversely rotated each other accompanied by the advance of the base material film 2.
