Abstract

To provide a core of a film, quickly coping with setting and dirt of a shock absorbing layer at a low cost without generating an end face step mark in a core part. In this core for a film, an elastic layer is bonded to the surface of a cylindrical body to freely adhere to and separate from it. The elastic layer is formed of a sheet containing foam resin or elastic resin. In the core, at a joint of the sheet, the face direction of the end face of one sheet is oblique to the face direction of the surface, and the end face of the sheet 1 is parallel to the end face of another sheet opposite thereto.
