In manufacture of a polyimide film, self-supporting film is heated with both ends in a width direction held and carried by the tenter apparatus. The tenter apparatus has a guide member placed on each side of a carry path for the self-supporting film and a pair of tenter chains each moved along the guide member and each including a film holding mechanism for holding an edge portion of the self-supporting film. The tenter chain has a rotating body supported rotatably around a shaft member extending in a direction in parallel with a carry face of the self-supporting film and perpendicular to a longitudinal direction of the guide member for movably supporting the tenter chain. The shaft member is directly or indirectly fixed to a member identical to a member to which the film holding mechanism is fixed.
