Abstract: A sheet of staples (11) are formed by arranging a plurality of straight staples (1) in a row like a sheet of paper, and a staple set (10) is formed as a result of connecting them to each other by gluing a at least uniaxially oriented film (12) on at least one surface of the sheet of staples (11) so that the longitudinal direction of the straight staple (1) coincides with the orientation of the film (12).
