description A core for winding a prism sheet film is provided to minimize transcription generation due to a step difference among a tape, the film, and the core, and to prevent elastic deterioration in high temperature by using heat resistant sponge as an elastic member. A core(12) for winding a prism sheet film(10) comprises an inner paper(13) and an elastic member(14). The inner paper is provided with a hollow portion in the inside. The elastic member capable of being extended and contracted is adhered in an outer circumferential surface of the inner paper in a circumference direction. Thickness of the inner paper is 5 to 30mm.
