Abstract (en)
[origin: EP2684828A1] A film winding core (10) includes a core body (12) having a tubular shape and a plurality of film supporting portions (14) protruding from an outer peripheral surface (12p) of the core body (12). The film supporting portions (14) support a film (18) at a position away from the outer peripheral surface (12p) of the core body (12). Each of the film supporting portions (14) is made of an elastic material such as sponge, rubber, or foam, and has a shape of a semicircular column, a rectangular column, or a hollow semicircular column. Even if the film (18) wound on the core (10) contracts during storage, the film (18) and the core body (12) do not come into close contact.
