To provide a film separator capable of efficiently separating a film stuck to a glass substrate via a pressure sensitive adhesive, while holding a stable separation state, without making the pressure sensitive adhesive remain on the substrate.

This film separator separates the film 2 stuck on a substrate 1 surface via the pressure sensitive adhesive from the substrate; and has a placing tray 10 placing the substrate stuck with the film and an air shaft 20 having a sandwiching part on the outer periphery; and separates the film from the substrate by moving the air shaft while rotating by sandwiching a part of the film by a sandwiching part of the air shaft.
