PROBLEM TO BE SOLVED: To provide a file having a constitution making it possible to surely hold sheets or the like without using a filing implement, in the case of holding the sheets or the like in small numbers. SOLUTION: A flap part 2 that can be opened and closed between a position of unfolding and a position of closure is provided on the open end 1a side of a back cover 1B, while a stepped part 3 for preventing positional slippage of sheets Y or the like is provided on the open end 1b side substantially perpendicular and adjacent to the open end 1a. The opposed edge parts 3a and 2a of the stepped part 3 and the flap part 2 are so designed as not to interfere with each other.
