FILM WINDING CORE, AND WOUND FILM BODY USING SAME

摘要

A film winding core (10) of the present invention includes a core body (12) and a plurality of film supporting portions (14). The core body (12) has a tubular shape. The plurality of film supporting portions (14) are provided around the core body (12). The film supporting portions (14) protrude from the outer peripheral surface (12p) of the core body (12) respectively at a plurality of positions in a rotational direction of the core body (12) so that a film (18) is supported away from the outer peripheral surface (12p) of the core body (12). Each of the film supporting portions (14) is made of a material that can be deformed when the film (18) is wound on the film winding core (10).
