DOCUMENT FILE

PROBLEM TO BE SOLVED: To provide a document file in which the structure of a substrate is simplified by bringing a document holding part into contact with the substrate, and forming an elastic slider so that it holds the document holding part and the substrate and it can be slid and moved in a direction nearly intersecting one side of the substrate while being in contact with the document holding part, the surface opposed to the surface in contact with the substrate, and a projection part.SOLUTION: The document holding part (40) is brought into contact with the substrate (20) to be temporarily fixed to the substrate (20) by penetration of the projection part (70) through a hole part (26) opened on the substrate (20). The elastic slider (50) holds both of the document holding part (40) and the substrate (20). When the elastic slider (50) is slid and moved in a direction approaching the one side of the substrate (20), the elastic slider (50) presses a first flat part (80) to hold a document (30) and when it is slid and moved in a direction separating from the one side of the substrate (20), the elastic slider presses a second flat part (81) to release the held document (30).
