A gland packing provided in a fluid apparatus such as a pump and compressed in an axial direction so as to prevent penetration leakage of a fluid is provided. The gland packing (3) has a packing base material (11) of a predetermined length including a band-like flat braid (12) braided by moving a plurality of yarns (13) along one track (K). The band-like packing base material (11) is shaped into a ring by abutting longitudinal ends (12a and 12b) of the packing base material (11) so that a width direction thereof is parallel with a packing axial direction, and is then compressed in the axial direction, whereby the packing base material (11) is overlappingly folded in a packing axial direction, with a longitudinal direction of the packing base material (11) has a direction of folding lines (14)
