Abstract

In order to newly provide a folder that facilitates insertion of a document fastener into a narrow slit and that is improved in durability by making use of a property of a document fastener whose folded state can be kept due to resin, the document fastener is so arranged to comprise a plate material (a) made of resin having a body part () extending longitudinally and a pair of folded pieces () extending from the body part (), wherein a thickness of both end portions () of the plate material (a) is formed to be thinner than a thickness of other portions of the plate material (a), a boundary () between the body part () and the folded piece () is made to be foldable, and the folded state on the boundary () can be kept by making use of the properties of the resin itself.
