PROBLEM TO BE SOLVED: To provide a file capable of easily spreading binding sheets flat when a binding body is opened. SOLUTION: This file is provided with a binding body 30 superimposed with many binding sheets, a curved retaining portion 50 curved toward the direction of pocket sheets 18 as the binding body extending when the cover is opened, and a curved subsidiary portion which fixes its back into an optional form. The binding body 30 is adjacently provided to the curved retaining portion 50 by forming an arch-shape toward the direction of a front cover portion and a back cover portion extending from the inner side of the spine portion, and the curved retaining portion 50 is connected with the width shorter than the width of the spine portion to the inner side of the curved subsidiary portion at the outer side of the curved retaining portion to enable the end edge adjacently provided on the binding body to curve.
