PROBLEM TO BE SOLVED: To provide reduction in thickness of a disc stopper while maintaining workability of fixing a disc stopper to a turntable and ensuring a prescribed thickness of a grip layer.SOLUTION: A disc stopper precursor 2 is for forming a disc stopper 1 with a lamination structure at least comprising an adhesive layer 11 and a grip layer 12. The disc stopper precursor 2 has a hard layer 23 formed of a material harder than a grip layer 22 and the hard layer 23 is integrated by lamination to the grip layer 22 on the other side of the adhesive layer 21. The disc stopper precursor 2 is stuck to a turntable T and then the hard layer 23 is removed by cutting while turning the turntable T to expose the grip layer 22. |
