Provided is a sheet stopper which has a simple structure, is not easily damaged, and has a low manufacturing cost. Kind Code: A1 A cylindrical sheet stopper for fixing a sheet-like member to a pillar member by fitting the sheet-like member to the pillar member by sandwiching the sheet-like member therebetween. The holding portion 5 has an opening 80 that opens in the axial direction, and an inner peripheral surface 60 that fits on the surface of the support member with the sheet-like member interposed therebetween. The locking portion 50 is formed, and the width of at least one of the axial end portions 51 of the locking portion in the opening direction is small.
