PROBLEM TO BE SOLVED: To newly provide a folder which can be easily inserted into a thin slit and enhance durability by using the characteristic of a document fastener holding the folded condition by a resin. SOLUTION: The folder comprises a resin-made plate material (a) including trunk part (11) extending in a longitudinal direction and a pair of fold-back pieces (12) extending from the trunk part (11), wherein the thickness of each of both end sections (14) of the plate material (a) is rendered less than at other sites, and wherein the border (13) between the trunk part (11) and each of the fold-back pieces (12) is rendered freely bendable so that in dependence upon the properties of the resin per se, the state of bending at the border (13) can be retained.
