<p>PROBLEM TO BE SOLVED: To provide a wind-up reel capable of smoothly winding up metallic foil or an electrode material, and simply positioning a winding core forming body.SOLUTION: A wind-up reel 20 is equipped with a cylindrical winding core portion 21 wound with an end material 15 on its outer peripheral surface. The winding core portion 21 is formed by integrating cylindrical first and second winding core forming bodies 30 and 40 divided in a direction diagonally intersecting an axial direction of the winding core portion 21. The first and second winding core forming bodies 30 and 40 have first and second inclined surfaces 37 and 47 positioned on both divided surfaces. In the first and second winding core forming bodies 30 and 40, the maximum length from one end to the other end in the axial direction is longer than length in a lateral direction of the end material 15. The first winding core forming body 30 has a guide recessed portion 37a on the first inclined surface 37, and the second winding core forming body 40 has a guide projecting portion 47a engaged with the guide recessed portion 37a on the second inclined surface 47.</p> |
