To provide a bookmarker which is held stably by the lamination material of a laminate without using an adhesive, does not come off easily from the laminate, and is unnecessary to be attached again to the laminate every time when its use such as reading is interrupted.

A bookmarker 1 comprises inner markers 4, 5 formed to fix a part to be held in a laminate of lamination materials such as paper by pinching it with sheets and a main body marker 6 which is formed on the outside of the marker 5 to face markers 4, 5 and is in contact with the marking position of the laminate. In a part of a protruding part 2 protruding outward at one end of the markers 4, 5, with the marker 6 facing the marker 5, one end of the marker 6 is fixed. The marker 6 is formed in contact with the marking position of the laminate across the marking position of the laminate to which the marker 6 is attached at an appropriate distance from the position to be held of the laminate.
